How are the functions of the brain and heart different? (2 points)
a
The brain cleans the blood before it is distributed to all parts of the body, while the heart passes oxygen into the blood.
b
The brain pumps blood to all parts of the body, while the heart filters the blood before it is distributed to all parts of the body.
c
The brain reduces the sugar level in the blood, while the heart helps break down the food into smaller pieces.
d
The brain sends and receives messages through the spinal cord and the nerves, while the heart pumps blood to all parts of the body.

1. What are metabolic wastes?
2. Which are the main organs of the excretory system?
Answer:
1. Metabolic wastes or excrements are substances left over from metabolic processes which cannot be used by the organism, and must therefore be excreted.
2. Organs of excretion include the skin, liver, large intestine, lungs, and kidneys.

Using the concept of natural selection, explain how giraffes evolved to have long necks over time. Be sure to write out the 3 steps of natural selection.
Answer:
Giraffes probably used to have short necks. Over time, since the branches of trees or plants were out of their reach, they adapted to this by having a longer neck. Those with longer necks are able to reach the food and eat it that those with short necks could not. Obviously, those with longer necks are able to survive and therefore reproduce. Because of reproduction, they are able to pass on this characteristic that allowed them to survive on to their offspring. This leads to offspring doing the same and over time, affecting the entire population of giraffes and soon evolving giraffes. This is natural selection doing its work in the evolution of long necks in giraffes.
Explanation:
Variation. Organisms (within populations) exhibit individual variation in appearance and behavior. These variations may involve body size, hair color, facial markings, voice properties, or number of offspring. On the other hand, some traits show little to no variation among individuals—for example, number of eyes in vertebrates.
Inheritance. Some traits are consistently passed on from parent to offspring. Such traits are heritable, whereas other traits are strongly influenced by environmental conditions and show weak heritability.
High rate of population growth. Most populations have more offspring each year than local resources can support leading to a struggle for resources. Each generation experiences substantial mortality.
PICTURE BELOW / Which phase of cell division is shown?
A. metaphase
B. anaphase
C. telophase
D. prophase
The phase of cell division that is showing here is prophase. The correct option is D.
What is cell division?Cell division occurs in two stages: mitosis and meiosis. When most people say "cell division," they're referring to mitosis, the process of creating new body cells.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Cell division is the process by which new cells are formed in the body for growth, repair, and replacement. This process involves the division of nuclear material as well as the division of cytoplasm.
Prophase, prometaphase, metaphase, anaphase, as well as telophase are the stages. Cytokinesis is the final physical cell division that occurs after telophase and is thus sometimes considered a sixth mitotic phase.
Prophase is the phase that is shown in the image as it involves condensing of chromatids and movement if centriole to opposite pole.
Metaphase is the phase in which the chromosomes align at the equator and anaphase separate the chromatids and move towards opposite pole.
Thus, the correct option is D.

When you are writing alleles, dominant alleles get what?
Plz I don't wanna fail ill give brainliest
Answer:
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

Answer:
The child will have a 100% percent chance of a widow peak and o% chance of an straght hair.
Answer:
100%, 0%
Explanation:
When you combine the t's and T's in a Punnet Square, you get 100% of a chance of getting a widow's peak. This is because there are 2 capital Ts on one side, which combines at least 1 capital T with a lowercase t.
And, as you remember, a genotype has to have at least 1 capital for it to be a dominant one.
