Answer:
D:Arteries
Explanation:
Arteries carry oxygenated blood away from the heart to the tissues of the body. Veins carry blood depleted of oxygen from the same tissues back to the heart. The arteries are the vessels with the "pulse," a rhythmic pushing of the blood in the heart followed by a refilling of the heart chamber.

Consider this animal cell.
The organelles in an animal cell are labeled. Part D are stacked tubular structures.
Which organelles are labeled D, and what is one feature that distinguishes them from the other labeled organelles?
chloroplasts; the only organelles that produce sugars from sunlight
ribosomes; only found in animal and bacterial cells
centrioles; found in animal cells but not plant cells
mitochondria; the only energy-generating structures found in cells
The table lists some organelles and functions. Only one pair is correctly matched.
Functions of Organelles
Organelle Function
Nucleus Directs cell activity
Endoplasmic reticulum Breaks down sugar molecules to supply energy
Golgi apparatus Supports and protects organelles in the cell
Lysosome Produces proteins for the cell
Which organelle in the table is correctly matched with its function?
nucleus
endoplasmic reticulum
Golgi apparatus
lysosome
The function and the nucleus are appropriately matched. The nucleus, which serves as the cell's command centre, controls every activity. DNA and RNA, which make up genetic material, are in charge of encoding the instructions necessary for the cell to carry out its duties.
What happens in the case of nucleus in the cell division ?In addition to directing the replication of genetic material and the generation of new cells, the nucleus is involved in cell division. Additionally, the endoplasmic reticulum is well suited to its function.
A network of interconnecting tubes and sacs called the endoplasmic reticulum is in charge of the synthesis, processing, and movement of proteins and other chemicals inside of the cell. In order to provide the cell energy, it also breaks down sugar molecules.
The function of the Golgi apparatus is appropriately matched. The sorting, processing, and packaging of proteins and other molecules is carried out by the Golgi apparatus, a network of flattened sacs and tubes. By giving the organelles a protective covering, it also helps to sustain and safeguard the organelles within the cell.
The function of the lysosome is mismatched with it. The digestive enzymes in the lysosome, a membrane-bound organelle, are in charge of dissolving and recycling cellular waste and damaged organelles. It doesn't make cell-specific proteins.

How long ago did the first animals adapt to living on land?.
Answer:
440 - 410 million years ago
Explanation:
Whatever their origins, animals may have ventured onto land early in the Cambrian. Previously scientists believed that animals did not begin to colonise the land until the Silurian (440 - 410 million years ago).
What would happen if the concentrations of carbon dioxide and methane rose too high?
Answer:
I'm assuming this means concentrations of the atmosphere*
Explanation:
Carbon dioxide are both considered greenhouse gasses. This means whenever they are in the atmosphere, they absorb heat from the sun and trap it within the atmosphere. In general, greenhouse gasses are a good thing. They trap heat in the Earth during nighttime so we do not freeze when we don't have the sun. However, since the Industrial revolution, the overuse of fossil fuels which are made of carbon and sometimes have high methane concentrations have lead to an excess amount of these gasses in our atmosphere. If concentrations become too high, the Earth's climate will continue to display higher average temperatures, leading to a complete change in our environments as once glacial areas will begin to display more temperate climates, and temperate and warm climates will become even hotter. Ecosystems in every area will be severely damaged, with many species likely facing extinction. Additionally, sea levels will rise much higher, both due to the melting of glaciers into the ocean and also because warmer climates will make the ocean warmer, meaning the molecules of water will spread farther apart and increase the volume of the ocean.

Hormones have three ways of interaction that affects how a cell can give.
Antagonistic
One hormone has the opposite effect of another one. For example, when glucose levels are high, our body releases insuline so that our body can store it for later. However, when glucose levels are low, our body releases glucagon to release the storaged glocose.
Permissive
The release of one hormone allows the second one to act in a different organ. For example, the hypothalamus releasing TRH, which affects the hypofisis releasing TSH, and his hone affects the tyrod gland, which will produce T4 and T3.
Synergistic
It is an effect that happens when two hormones with a similar effect act together, amplifying their effect. For example, the increasing levels of testosterone and FSH together allow for sperm production.

Brown coat color rabbits possess the dominant allele B, and white coat color rabbits possess the recessive allele b. If the frequency of the allele for white coat color is 0.04, what is the frequency of the dominant allele in the population?
Assuming Hardy-Weinberg equilbrium, we have
p + q = 1
where p = frequency of dominant allele and q = frequency of recessive allele. So
p = 1 - q = 1 - 0.04 = 0.96
Consequently we have
• p² = 0.9216 = frequency of hom ozygous domininant genotype
• pq = 0.0768 = frequency of heterozygous genotype
• q² = 0.0016 = frequency of hom ozygous recessive genotype
since
p² + 2pq + q² = 1

The fibrocartilage pad between the medial condyle of the femur and the medial condyle of the tibia is called the __________.
Medial meniscus are fibrocartilage attached to the tibial collateral ligament, that is, between the medial condyle of the femur and the medial condyle of the tibia.
What is medial meniscus?It is an articular fibrocartilage that extends medially across the knee joint, where it attaches to the tibia anterior to the insertion of the anterior cruciate ligament.
This in the middle zone has continuity with the deep portion of the medial ligament, being well attached to the tibia and femur and acting as a cushion and distributing the weight of the femur.
Therefore, we can conclude that the medial meniscus are fibrocartilage attached to the tibial collateral ligament, that is, between the medial condyle of the femur and the medial condyle of the tibia.

Predict the movement of water in the picture
Answer:
The water will move out of the cell
Explanation:
This is due to osmosis. We can infer that there is some solute outside that is making the water outside into 75%. As from rules of osmosis, higher concentrations of water will move to lower concentrations of water. So, since the cell has a higher water percentage, water will move from the cell to the outside environment to maintain homeostasis.

Are heated air and wind shear the cause for severe storms? Explain.
Answer:
Yes, they are very much the main cause of severe storms because the heat molecules get into the atmosphere and clouds, causing chemical reactions and damage. At some point in time, the energy built up, as well as the damage done, must undo itself. This is done through a storm. It is the environment's way of cleaning itself.
As a part from this video below states, wind shear is a leading cause in severe storms.

How does resource availability, such as water, drive competition?
Answer:
If there was less water, then there would be more competition, since now a population has to live off of a little bit of water. Similarly, a lot of water would result in less competition, since now the water will basically be more available, and not something that two animals might have to fight over.
