Which statement correctly describes a level of organization in the human circulatory system?
Answers:
Cells are only present in tissues.
O Organ systems are only present in cells.
Tissues are made up of many organs.
Organs are made up of many tissues.
Nitrogen is necessary for building these two organic molecules:
O carbohydrates & lipids
carbohydrates & proteins
nucleic acids & lipids
nucleic acids & proteins
Answer:
D
Explanation:
the major constituents of carbohydrates are carbon, oxygen, and hydrogen while protein contains nitrogen,carbon, hydrogen,and some mineral elements, and lipids major constituents are carbon, hydrogen and little oxygen.
the nucleic acids are packed with histones, which is proteinous, and contain nitrogen too
Is a reflex part of the central
nervous system, the peripheral
nervous system, or both? Explain.
Answer:Because the peripheral nervous system transmit reflex impulses from sense organs to central nervous system and then back to the sense organs. So both the Central nervous system and the peripheral systems are involved.
To understand a bit better.....
One of our body parts consists of a nervous system it is a complex network of neurons and cells that carry pieces of information to and from the brain and spinal cord to various parts of the body.
So in conclusion...
Yes! The Central nervous system and the peripheral systems are involved!So therefore your question is correct!
Hope this helps!

why is water molecule called polar
Answer:
Since oxygen has a higher electronegativity than hydrogen, the electrons of the molecule tend to group closer to the oxygen than to the hydrogen atoms. as well as , water is said to be a "polar" molecule, which means that there is an uneven distribution of electron density.

7. What system in animals has the transport of nutrients and other materials as its main
function?
A. Circulatory
B. Nervous
C. Endocrine
D. Integumentary
Answer:
Circulatory System
Explanation:
The Circulatory System transports oxygen, carbon dioxide, nutrients, waste products, immune components, and hormones. Major organs include the heart, capillaries, arteries, and veins. The lymphatic system also transports excess fluids to and from the circulatory system and transports fat to the heart.
A biologist reads an article in a scientific journal that describes how the legs
of different organisms look and function differently, but appear to be
constructed from the same basic bones. He compares a drawing of the
skeletal structure of a porpoise's fin with one of an elephant's leg. (7A)
What aspect of the theory of evolution do these drawings support?
Answer:
Homology
Explanation:
The aspect of the theory of evolution that the drawings support is homology. Homologous organs are organs of different organisms that look similar in structure but perform different functions in reality.
Organs that are built on the same or similar basic plans in the same organisms but perform different functions are thought to have been from the same ancestor. Hence, homology or homologous organ represents one of the evidence used to support the theory of evolution which opines that all living organisms descended with modifications from common ancestors.
which of the following are key elements of darwin's theory of evolution by natural selection?
Answer:

The three pillars of Darwin's theory of evolution are genetic variety, fitness, and adaptation. Overproduction and competition are other crucial components of this process.
What Darwin's theory of evolution by natural selection?Charles Darwin's theory of evolution is known as natural selection. Due to the limited supply of resources in nature, animals have inherited traits that aid in both survival and reproduction.
Typically, produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this Overproduction is that those people who have the highest level of environmental genetic fitness will have offspring who are better able to compete in that environment.
Therefore, Genetic variation, fitness, and adaption are all factors in Darwin's theory of evolution.Overproduction and competition are other crucial components of this process.

This image shows the relative frequency of banded and non-banded snails in a population. If the frequency of banded snails decreased to 60% and non-banded snails increased to 40%, would you consider the population to be evolving?
Answer:
The nonbanded are evolving and the banded are not. It looks like something is either eating the banded shrimp and not the unbranded. Or the unbranded shrimp are eating the banded shrimp.
Explanation:

As per the image of the single-gene trait the phenotypes are shown as per those with and without bands. The phenotypes without band are 20% and that of with band is 80%.
If the population of the snails gets reduced by 60% and non-banded gets 40% then the population that evolves would be that of the nonbranded snails will increase.Learn more about the relative frequency of banded.

Some people call Earth the "Blue Planet," why do you think this is? Of all the water on Earth, only about 1% is available for human use. WHY?
Answer:
I think it's not because of the water we use it's the water we have.
Explanation:
Because our planet is made up of 75% water it is naturally the first thing to recognize.

Which statement best describes codominance and incomplete dominance?
Answer:
This question lacks options, the options are;
A) In codominance and incomplete dominance, both of the alleles are dominant.
B) In codominance and incomplete dominance, neither of the alleles are dominant.
C) In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.
D) In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.
The answer is C
Explanation:
Codominance and incomplete dominance are both a type of non-mendelian inheritance pattern i.e. patterns of inheritance that do not follow mendelian principles.
- In codominance, the alleles of a gene are both dominant and hence, both express themselves simultaneously for that trait. An example is the alleles A and B of the blood group in humans where both A and B are dominant in the gene.
- In incomplete dominance, neither of the two alleles of gene is dominant and none is recessive either. This means that the two alleles blend together to form an intermediate phenotype in a heterozygous offspring. An example is the pink flower in four o'clock plants resulting from the blending of red and white alleles.

Describe how the egg gets from the ovary to the site of fertilisation.
Answer:
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
