Answer:
Biology is an interesting subject that has been intriguing scientific minds for several centuries
Explanation:
Despite exponential developments in technology over the past few centuries, the origin of life on earth is still one of the biggest mysteries yet to be unraveled.
The basis of our very origin and existence on earth lies within the depths of the biological sciences. Biology has an endless array of species( at least as of now because there are an estimated 8.7 million species on earth out of which only 1.9 million species have been discovered, so there is a long way to go!).
Every creation which is a part of nature is so adorable and unique in its own way.
Biology exists every second - when we inhale and exhale each time, respiration is taking place within our bodies, each cell receives oxygenated blood and releases carbon dioxide and other excretory wastes.
Let aside other species, we haven't yet understood our own bodies completely!!How is it that our hearts work so tirelessly throughout our life span, how is it that we are able to interpret even minute emotions and gestures without even understanding the mechanism behind it!.How is it that each one of us is able to perceive things differently?What exactly is consciousness?..The list of questions seeking their answers is endless!
Biology helps us to sort things out and find answers to such questions.
Humans aren’t the only living things biology is concerned with. It also tells us all about plants and animals – how they live, what they’re made up of, and how they interact with mankind and each other. This enables us to make the most of our planet’s natural resources while trying to minimize the impact we have on the environment.

What is the element or compound in the Phosphorus Cycle and why is it important to living things?
Answer:
Phosphorus is an essential nutrient for animals and plants. It plays a critical role in cell development and is a key component of molecules that store energy, such as ATP (adenosine triphosphate), DNA and lipids (fats and oils). Insufficient phosphorus in the soil can result in a decreased crop yield.
Explanation:
Answer:
Thus, phosphorous is crucial to living organisms because ATP is crucial. Phosphorus is also important because it makes up our DNA. Phosphate is part of the so-called ladder legs which Adenine, Thymine, Guanine, and Cytosine bind to see. It holds this same job in RNA.

The Wunderlich Farms Boer Goat has a 4 chambered stomach and chews it's cud to assist with digestion. What type of adaptions are these?
A. 4 chamber stomach = behavioral and chewing cud = internal structural
B. 4 chamber stomach = external structural and chewing cud = behavioral
C. 4 chamber stomach = internal structural and chewing cud = external structural
D. 4 chamber stomach = internal structural and chewing cud = behavioral
Answer:
The answer is option A "4 chamber stomach = behavioral and chewing cud = internal structural"
Explanation:
Goats and other ruminants do not digest food directly as they eat their food and the reason is that ruminants do not have the enzymes that are necessary for breaking down the food directly as they eat so digestion in ruminants and particularly Goats has to undergo processes or procedures before the final digestion takes place.
All the processes in digestion for ruminant animals takes place in their four chambered stomachs which are the Rumen, Reticulum, Omasum and Abomassum.
In the four chambered stomach of Goat, the type of adaptation is behavioral and chewing cud which is the internal structure.

is biological control effective than chemical control of crop protection?
Answer:
No
Explanation:
There are different ways or methods of protecting crops from pest and disease infestation. Two of those ways as mentioned in this question are the chemical control and biological control. Biological control of crop protection involves the use of natural enemies of crop pests, which happens to be living or biotic organisms while chemical control entails the use of pesticides and herbicides to control crop pests and diseases.
Among these two methods, the chemical control is more effective because it yields instantaneous results and gets rid of pests and diseases faster. However, in terms of sustainability, the biological control method is more eco-friendly. Hence, based on this question, biological is not more effective than chemical control of crop protection.
As thermal energy is added to a substance, which of the following changes can be predicted?
O
Spacing between particles will decrease
Vibration of individual particles will increase
Temperature of the substance will decrease
The pressure of the air around the substance will increase
Answer:
Vibration of individual particle will increase
Explanation:
This is due to the fact that whenever any substance of matter is increased in temperature, the atoms begins to move away from each other. Take for instance an ice cube for example, when an ice cube (a solid) is heated it becomes water, (a liquid). Proving that when a substance is heated, no matter the density of the material, the individual particles, or atoms, begins to spread apart.

How do oceans contribute to creating winds?
A.Ocean currents create momentum that pull air with them.
B.Ocean water vapor pushes air causing it to flow in different directions.
C.Ocean energy is transferred to or from the air creating density differences.
D.Ocean water vapor eventually condenses into clouds and wind.
Answer:
Explanation:
Ocean energy is transferred to or from the air creating density differences.
Oceans contribute to creating winds as ocean energy is transferred to or from the air, creating density differences. The correct option is c.
What is ocean energy?The ocean waters are continually changing. Wind, water salinity, temperature, ocean floor topography, and the earth's rotation all influence ocean current flow patterns.
The majority of ocean currents are caused by wind and solar heating of surface waters near the equator, while some are caused by density and salinity fluctuations in the water column. In contrast to tidal currents along the shore, ocean currents are typically consistent and travel in one direction.
The transfer of energy from the ocean to the atmosphere causes the atmosphere to cool. The energy travels in a disturbance, which in an ocean is a wave, therefore the wave generates energy and transports it through the water.
Therefore, the correct option is C. Ocean energy is transferred to or from the air, creating density differences.

Which of the following statements BEST describes ASEXUAL reproduction?
Question 8 options:
A single-celled organism uses meiosis to create two identical copies of itself.
Two multi-celled organisms uses meiosis and fertilization to create a unique offspring.
Two multi-celled organisms use mitosis and fertilization to create a unique offspring.
A single-celled organism uses mitosis to create two identical copies of itself.
The statement “ A single-celled organism uses mitosis to create two identical copies of itself” best describes asexual reproduction
The statement which best describes the mode of asexual reproduction is that a single-celled organism uses mitosis to create two identical copies of itself. Thus, the correct option for this question is D.
What is Asexual reproduction?Asexual reproduction may be characterized as a mode of reproduction in which a new offspring is produced by a single parent. This type of reproduction does not involve the fusion of gametes or a change in the number of chromosomes.
Asexual reproduction is homologous to the process of mitosis. This is because both of them involve the production of two identical daughter cells from a parental cell.
While meiosis produces four daughter cells which are genetically unique to the parent cells. It is the characteristic feature of sexual reproduction that is opposite to an asexual one.
Therefore, the correct option for this question is D.

Crossing over
Mitosis
Crossing over is when the alleles cross over and pair up, resulting in the genotype for an offspring.
What is Crossing over?When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the formation of egg and sperm cells (meiosis).
This mechanism leads to novel allele combinations in the gametes (egg or sperm) generated, ensuring genetic variety in any baby born.
Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes — one from the mother and one from the father — line up, parts of the chromosome can be switched.
Therefore, Crossing over is when the alleles cross over and pair up, resulting in the genotype for an offspring.

Explanation:
In a certain plant, the allele for red flower color (R) is dominant over the allele for white flower color (r). A cross is performed between a plant with red flowers and a plant with white flowers. The offspring are 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants?
Answer:
Rr and rr
Explanation:
The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).
Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr).
Rr x rr
Rr Rr rr rr
Rr = red
rr = white
If the red parents is true-breeding
RR x rr
Rr Rr Rr Rr
All their offspring would be red without any white flower color.
Hence, the genotypes of the parent are Rr and rr.
