Analyze the effects of DNA mutations
on the
of an organism.

Answers

Answer:

DNA mutations or Chromosomal mutations are also called chromosomal aberrations, chromosomal abnormality, or chromosomal disorders, all indicating a possible alteration in the morphology and structure of the chromosome.

DNA mutations lead to abnormalities in the function of the cell and organism, as chromosomal or DNA mutations can result in abnormal gene numbers or positions.

These are known to cause different genetic diseases that can be hereditary and are transferred from one generation to another.

These mutations, however, do not always affect the functioning of the cell as some mutations might affect regions of chromosomes that do not make up the genetic makeup of the organism.

Even though gene mutations are usually more severe than chromosomal mutations, some chromosomal mutations might result in gene mutations.

A group of students wants to study the structures of animals in the desert. One question they should ask is-
How long do the animals live?
Can you buy the animals in pet stores?
How do the animals satisfy their need for water?
How many offspring do the animals have?

Answers

From studies and research, I believe the proper question would be:

"How do the animals satisfy their need for water?" or "How long do the animals live?"

Explanation 1:

When studying the desert, asking "Can you buy the animals in pet stores?" is not going to help you find information about the desert because it is not a question to get information about the desert, only information if you just buy it at your local pet shop.

Explanation 2:

Asking "How many offspring do the animals have?" does help us learn about animals, but we are trying to find information on the structure of the desert in which the animals live in. We are not looking for how many children the animals will have because it doesn't fully relate to the question we would be asking.

Side Note: Offsprings mean children.

There is a direct relationship between the number of pollinating plants and the number of honeybees. Each population is dependent on the other for their survival and ultimately reproductive success.

Answers

Answer:

Both depends on one another.

Explanation:

Yes, there is a direct relationship between the number of pollinating plants and the number of honeybees because honeybees are insects that are responsible for pollination in the flowering plants. The population of flowering plants also has a great effect on the survival of honeybees because these flowering plants provides food in the form of nectar on which these honeybees survive and make honey from it. So we can say that both flowering plants and honeybees depends on one another for the successful growth and development.

2. Which explanation for the increase in genetic diversity of this red panda population is supported by this data?

(1 point)

Red pandas in this population have encountered new predators due to the increase in deforested land, and this new predation pressure has selected for different adaptations.

Red pandas in this population have increased the number of cubs birthed by each mother every year, and this increase in population has resulted in more genetic diversity.

Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.

Red pandas in this population have started eating a new diet due to the increase in deforested land, and the new dietary conditions have selected for different adaptations.

A swamp that is being drained in order to build houses.

A forest that is being converted into farmland.

A lake that is drying up due to shifts in river flow.

A desert that has existed for millennia.

Answers

Answer:

2. C - Red pandas in this population have encountered new environmental challenges presented by the increase in deforested land, and this has selected for different adaptations over time.

5. D - A desert that has existed for millennia.

Explanation:

2. Predation (A) and fertility (B) are easy scratch-off answers -- given the situation of deforestation, these factors will not influence genetic diversity. Although eating patterns can lead to new adaptations, the best answer is C because it results directly from the issue at hand: deforestation.

5. To limit the amount of population diversity, you would have to maintain the same environment as much as possible. In other words, migration and isolation lead to the creation of new species per Darwin's theory of Natural Selection. For that reason, the only plausible answer here is D.

18. Where does digestion of fat take place in our body?
19. What is the mode of nutrition found in human beings?​

Answers

Answer:

10. chlorophyll

11. There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.

12. Nutrition is necessary for the growth of new cells and the replacement or repair of worn-out cells. Nutrition gives energy for different metabolic processes in the body. Nutrition is required to produce resistance against different diseases.

13. trypsin

14. salivary amylase

15. Hydrochloric acid helps your body to break down, digest, and absorb nutrients such as protein. The hydrochloric acid found in the stomach facilitates digestion by disintegrating complex large food molecules into simpler molecules. The acid activates the pepsinogen enzyme required to digest proteins.

16. Saliva, the watery liquid produced by glands located under the tongue, is an essential component of the digestive process. Saliva is 98% water, so it moistens the mouth and helps compact food into softened particles for easier swallowing.

17. Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.

Explanation:

This is an example

A. The following food chain in a simple terrestrial ecosystem:

Grass → Grasshopper → Frog → Snake → Hawk

B. The energy flow will be directed as follows:

grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)

Food Chain:

Consider the following food chain in a simple terrestrial ecosystem:

Grass → Grasshopper → Frog → Snake → Hawk

In this food chain, the grasshopper is the major producer, the frog is the secondary consumer, the snake is the tertiary consumer, and the hawk is the quaternary consumer.

B. Flow of Energy:

The giant arrow representing the flow of energy through the food chain would start with grasses and progress through each trophic level. Energy moves along the food chain in a way that passes from one organism to another when it is consumed.

The energy flow will be directed as follows:

grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)

The arrows indicate that the sun's energy is taken up by the grass through photosynthesis and then transferred to each successive level when the organism consumes it.

Answers

Answer:RNA code for Amino Acids that make Proteins through the process of translation

Explanation:

During translation, tRNA recognizes the mRNA codons, complements them, and add the correct amino acid to the growing protein. CODON and PROTEIN are the missing words.

--------------------------------------------------------------------------

Protein synthesis

Occurs in two steps. Transcription and translation.  

TranscriptionmRNA syntheis

The first step before protein synthesis begins is to synthesize messenger RNA, mRNA.  

This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.  

 

Translation:

Cytoplasm stage

Translation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores.  

• Once in the cytoplasm, mRNA meets a ribosome, which is the primary structure for protein synthesis.

Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.  

• While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.  

                     →    mRNA is composed of different codons.  

                     →    Each codon is a chort sequence of  

                    three nucleotides that codes for one amino acid.  

                     →    When tRNA molecules recognize these                                                                                                  

                            sequencies, they add the correct amino  

                                   acid to the growing protein.  

Protein synthesis ends when the proteins passes through the Endoplasmic Reticulum and the Golgi complex for their final folding process.

Reproduction

A woman’s body prepares for a birth:

Answers

Answer:

Regulation / Homeostasis  you get too hot or too cold:

  If you get either too hot or too cold, sensors in the periphery and the brain tell the temperature regulation center of your brain—in a region called the hypothalamus—that your temperature has strayed from its set point.

Your diaphragm expands and contracts so you can breathe:

  When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

 

Nutrient Absorption

The reactants needed for cellular respiration are taken in and transported to your cells:

cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells.

Defense from Illness

A pathogen enters your body through a cut:

The skin and mucous membranes act as a physical barrier preventing penetration by microbes. If the skin is cut then the blood produces a clot which seals the wound and prevents microbes from entering.

Defense from Injury

A bunny is running away from a wolf:

Rabbits have keen senses of smell, sight and hearing, which help them defend themselves from danger. When they sense a nearby predator, they innately freeze in place to camouflage with the landscape.

Your hand gets too close to a flame:

Skin is difficult to ignite, and usually chars in the presence of heat. It takes up to 10 minutes of direct flame for skin to crack open and start leaking out rendered fat. Even if a horse's body started to leak fat, it would be unlikely to go up in flames on its own.

Reproduction

A woman’s body prepares for a pregnancy:

Every month, usually one egg grows within a structure called the egg follicle (a fluid filled sac that nourishes the egg). The follicle produces estrogen, which helps a woman's body prepare for pregnancy by growing a new lining for the uterus.

A woman’s body prepares for a birth:

As your body prepares for birth, your cervix — the muscular ring between your uterus and vagina — begins to soften, dislodging the mucous plug.
