Hi can someone please help me with this question Im struggling with it!!

Answer:

If dinosaurs still roamed the Earth today, my life would be drastically different. To begin with, my daily commute would look a lot different. Instead of cars, trains, and buses, I would likely have to hop on the back of a triceratops or a pterodactyl to get around. I would also have to make sure that I am aware of my surroundings at all times because I could easily become a snack for a hungry T-Rex.

On top of that, my living situation would be quite different. Instead of living in a typical house, I would have to live in a treehouse to avoid being eaten. Furthermore, I would have to be prepared to adapt to my environment as dinosaurs would be a constant presence in my everyday life.

In terms of my diet, it would be quite different as well. Instead of eating burgers and fries, I would have to find ways to hunt dinosaurs in order to have a balanced meal. This would require a lot of skill and would be a huge challenge for me. Additionally, I would have to be careful to only hunt certain species of dinosaurs as some could be very dangerous.

Overall, my life would look very different if dinosaurs still roamed the Earth today. From my transportation to my diet, almost everything in my life would need to be adjusted in order to survive in this new environment.

Explanation:

If substrate concentration is kept permanently high and the enzyme concentration is gradually increased, the rate of activity of the enzyme will increase and then level off. Option C

As the number of enzymes available to catalyze the reaction is abundant, the rate of the enzyme's activity will initially rise when the enzyme concentration is increased.

At the same time when the enzyme concentration continuously rises, eventually, all the substrate molecules will be consumed, and at this point, it gets stagnant where the pace of the reaction will decrease with the addition of more enzymes. This is referred to as the reaction's maximum velocity.

Hence, when the enzyme concentration is increasing steadily while still maintaining a persistently high substrate concentration, then the rate of the enzyme's activity will rise and then level off.

Therefore Option C is correct

Answer:

Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are the macromolecules that contain phosphorus. Phosphorus is an important component of the nucleotides that make up nucleic acids.

In DNA, the phosphate group is located on the 5' carbon of the sugar molecule, which is connected to the nucleotide base via a phosphodiester bond. The phosphate groups of adjacent nucleotides form the backbone of the DNA molecule.

In RNA, the phosphate group is similarly located on the 5' carbon of the sugar molecule, but RNA has a ribose sugar instead of a deoxyribose sugar. RNA also typically contains single-stranded nucleotides, rather than the double-stranded structure of DNA.

Overall, phosphorus plays a critical role in the structure and function of nucleic acids, which are responsible for storing and transmitting genetic information.

Explanation:

The characteristics that annelids share with flatworms and roundworms are as follows:

The statement that only ERCs are not transmitted to daughter cells during replicative aging is False.

The statement that old mother cells have a fragmented nucleolus because of highly accumulated ERCS is False.

Both ERCs (Extrachromosomal rDNA Circles) and nuclear DNA mutations are not transmitted to daughter cells during replicative aging.

ERCs are circular DNA molecules that accumulate in the mitochondria of cells during aging and can cause mitochondrial dysfunction. Mitochondria are only inherited from the mother cell during cell division, hence ERCs are not transmitted to the daughter cells during replicative aging.

Old mother cells have a fragmented nucleolus due to defects in the nucleolar organization rather than the accumulation of ERCs.

The nucleolus is a specialized structure within the nucleus responsible for ribosome biogenesis. During aging, the nucleolus becomes fragmented and disorganized, which can affect the production of new ribosomes and contribute to cellular dysfunction.

Cyanosis is characterized by bluish discoloration of skin and mucous membranes. Cyanosis is usually a sign of an underlying condition rather than being a disease in itself. The most common symptoms of the condition are bluish discoloration of the lips, fingers, and toes.  

Cyanosis can be evident at birth due to the presence of a heart malformation that permits blood that is not fully oxygenated to enter the arterial circulation. Cyanosis can also appear at any time later in life and often accompanies conditions in which lung function is compromised (resulting in an inability to fully oxygenate the blood) or conditions in which the heart's pumping function is compromised. The presence of abnormal forms of hemoglobin or other abnormalities of the blood cells can also sometimes cause cyanosis. The medical term for lowered oxygen level is hypoxia, the term anoxia refers to the absence of oxygen. Pseudo cyanosis is the appearance of cyanosis that is not associated with reduced oxygen delivery to the tissues. Most causes are related to the ingestion of metals (such as silver or lead) or drugs/toxins.

Plug-in hybrid electric vehicles (PHEVs) have both an electric motor and a gasoline engine, while electric vehicles (EVs) only have an electric motor powered by a battery. EVs typically have a larger battery capacity and range than PHEVs, which rely more heavily on their gasoline engines for longer drives. While the range of EVs can still be limited by the capacity of their batteries, they generally have a longer range on a single charge compared to PHEVs. However, it is worth noting that both EVs and PHEVs can vary in range depending on their specific models and battery capacities.

La cellule humaine comprend 46 chromosomes, porteurs du code génétique de l'espèce humaine. Le nombre de chromosomes est de 46 chez l'homme : 22 paires d'autosomes et 2 chromosomes sexuels ou gonosomes, XX chez la femme et XY chez l'homme.

Chromosomes present in the human body are in a pair of 23. These 23 pairs of chromosomes are also divided into two sub-division called autosome and sex chromosome. The autosome is 22 in pair and the sex chromosome are 1 in pair.

Autosomes help in inheriting the characteristics from parent to offspring, whereas sex chromosome help in determining the sex of the offspring. Therefore, the human haploid number is n = 23, haploid number refers to the  number of chromosomes present in a single set that is denoted by n. Each of these chromosome pairs exists with diploid cells.

Hence, humans are diploid containing 46 chromosomes that divide to half forming 23 pair of chromosomes.

Answer:

The answer is A

Explanation:

It wouldn't be B because it uses convection (Heat travels through a liquid or gas). In Bs case the heat travels through air.

It wouldn't be C because it also uses convection (Heat travels through a liquid or gas). Opposite from B the heat travels through liquid.

Finally it wouldn't be D because it travels through empty space, which uses electromagnetic radiation (Radiation is the transfer of heat energy through space). The heat travels through space not by direct contact.

The correct answer is Creativity helps scientists use appropriate methods to date rocks.

Scientists often need to be creative in their approach to research problems, including the dating of rocks. They may need to develop new techniques or adapt existing methods to fit specific research questions or situations. Creativity can also help scientists identify new areas of inquiry or make connections between seemingly disparate fields of study.

However, personal bias should not play a role in selecting methods to date rocks, as this could lead to inaccurate or misleading results. It is important for scientists to remain objective and follow established scientific protocols when conducting research.

It is also worth noting that scientific methods and explanations are not necessarily unchangeable. Science is a constantly evolving field, and new discoveries or advancements in technology may lead to changes in the way research is conducted or how phenomena are explained. This is why scientific knowledge is always subject to revision and refinement as new evidence comes to light.

Answer: C. Two or three

Explanation:

The correct statement from the options about protons, electrons, and neutrons are:

D. None (The idea that matter is 'continuous' was proposed by Aristotle)

D. Democritus

B. Neutron and proton

C. Mass number

Protons, electrons, and neutrons are subatomic particles that make up atoms.

Protons are positively charged particles located in the nucleus (center) of an atom. The number of protons in the nucleus determines the element that the atom represents. For example, all carbon atoms have six protons in their nucleus, while all hydrogen atoms have one proton.

Electrons are negatively charged particles that orbit around the nucleus of an atom. Electrons are much smaller than protons and neutrons and are responsible for the chemical properties of an atom. The number of electrons in an atom is typically equal to the number of protons, ensuring that the atom has no overall electric charge.

Neutrons are neutral particles located in the nucleus of an atom, with a mass similar to that of protons. Neutrons do not carry a charge, but they do affect the stability and mass of an atom. The number of neutrons in an atom can vary, resulting in different isotopes of the same element with different masses.

A premise that could be used to back up the conclusion that urchins are undergoing natural selection would be that urchins with short spines are extremely vulnerable to predators. Option C.

Urchins with short spines are extremely vulnerable to predators.

This is because natural selection is a process in which organisms with certain traits are better able to survive and reproduce than those without those traits, and those traits are then passed on to future generations.

In this case, the vulnerability of urchins with short spines to predators means that they are less likely to survive and reproduce, while those with longer spines are more likely to do so.

Therefore, the trait of long spines is being naturally selected for in the urchin population. The other options do not provide evidence for natural selection.

The data that supports this idea is wildebeest grazing behaviours assist reduce grass height and prevent fire spread.

Evidence 1: Wildebeest's grazing behaviour lowers grass height and inhibits the spread of fires. As indicated in the article, grazers like wildebeest eat the grass and minimise the fuel available for flames, which prevents fires from spreading and destroying the trees.

Evidence 2: Wildebeest migration patterns can result in a patchy mosaic of grass heights that influence how susceptible grass patches are to burning. According to the article, wildebeest migrate and produce a patchy mosaic of grass heights. This also means that some areas of the savanna are dense with more trees, while others have fewer trees.

As a result of their grazing practises and migration patterns, which support the preservation of a diversified ecosystem, wildebeest are a keystone species in the Serengeti. In the absence of wildebeest, grass height would rise, resulting in more frequent and destructive fires. The ecosystem's diversity would decline and the effect on the trees would be harmful.

Answer: Judy and her parents have an adaptation that helps them run from predators coming; this adaptation is called flight. Flight is an innate ability to fly away from danger using wings or other means.

What is adaptation?

Adaptation is the change process in an organism that helps it better survive in its environment. This can include behavior, physiology, and even genetic changes that allow an organism to better survive and reproduce. For example, a bird may migrate to a warmer place in the winter to escape the cold temperatures, or a plant may produce thorns to protect itself from being eaten by predators. Adaptation is an important factor in the survival of a species, as it allows populations to adjust to new environmental conditions. As environmental conditions change over time, adaptation can help species adjust to survive in the new conditions.

Flight is a common adaptation used by many animals, including Judy and her parents. Flight allows them to quickly fly away from predators to avoid being hurt or killed. They can fly away from danger in a matter of seconds, giving them a better chance of survival. Flight is an important adaptation that helps Judy and her parents stay safe and out of harm's way.
