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.

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
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.

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.
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!

3.In the same way coffee is a mixture of water caffeine and other components of coffee. It could be a homogeneous mixture (everything is completely dissolved in water or a heterogeneous mixture (some of the substances may not be fully dissolved; e.g., milk.)
Explanation:
I Couldnt Tell What were The Object aside From The coffe--or was Number 3 not coffe?? - anyways That Is all I can answer
The following mixtures are made by mixing the components with each other.
What are mixtures?A mixture is a substance comprised of two or more additional chemical compounds or substances that do not chemically combine. It is really the physical blending of two or more substances such that they may still be distinguished from one another when combined as solutions, suspensions, or colloids. Physical means can be used to separate them. The different components of any combination are not created via any sort of chemical transformation. As a result, each component's unique qualities are unaltered.
A mixture's constituent parts also do not combine chemically to form a new material, in contrast to a compound. Instead, they just combine while retaining their individual traits. The lemonade seen above is a mixture since the ingredients are not present in predetermined amounts. Even though it has more or less sugar or lemon juice, it will still be referred to as lemonade.
Therefore, mixtures are made by mixing the components together.

Answer:
Each daughter cell contains the same genetic makeup as the original parent cell
Explanation:
After the process of mitosis and cell division 2 new identical daughter cells are created. Each daughter cells contains the same number of chromosomes as the original cell. Therefore, each daughter cell has a complete copy of all the genes that the original cell contained. Making them identical to the original cell.

Explain what would happen to the number of rats if the eagles died from a disease.
Answer:
If eagles died of disease, the number of snakes that prey on rats will increase, which will decrease the number of rats. Also, eagles will cause the and rabbit population to increase, decreasing the plant population and therefore decreasing the rat population because of the lack of food.
tldr; rats will decrease if eagles died of disease.
Answer:
The rabbit population willl increase because the eagles are not present to feaast on them. The population of the snake will also increase since the Eagles are not present and the rat's population will increase as welll because it's only 1 animal who is eating them.

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.
Answer:
The correct answer is b
Need help. Will give brainliest. Answer all these questions.
Answer:
1. The daughter cells are genetically identical because they each contain the same diploid chromosome complement as the original parent cell. It can be seen in the stages shown above that mitosis maintains the chromosome number or complement of a cell.
2. Much of the growth in an adult is attributed to the growth plate in the bones, which is line of cells at each end of the bone that divides rapidly during puberty. As the bones elongate, the muscles also elongate as they are stimulated to grow by stretching and hormonal changes. When puberty is completed, the growth plate calcifies into solid bone and can no longer grow. Muscles can continue to enlarge with athletic activities and can sometimes split with excessive force, but muscle cells typically do not continue to divide. Cells such as your skin, hair, and interior mucus surface cells continue to divide because they are in direct contact with things from the outside world. Bone marrow also continually divides to produce red and white blood cells. Many other cells in your body do not continue cell division.
3. The number of Chromosomes stay the same when the cell divides because before a cell divides it produces new copies of the Chromosomes in the nucleus so when division takes place two genetically identical 'daughter cells', containing the same genes, are formed.
4. – in cells capable of dividing, the period between cell divisions is called interphase – cells spend most of their time in interphase because this is the phase where they perform their functions (obtaining energy, synthesizing products, repair damage, fight disease, duplicate their genetic material and get ready for division)
5. Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria. Many eukaryotic organisms including plants, animals, and fungi can also reproduce asexually. In vertebrates, the most common form of asexual reproduction is parthenogenesis which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited. While all prokaryotes reproduce without the formation and fusion of gametes, mechanisms for lateral gene transfer such as conjugation, transformation and transduction can be likened to sexual reproduction in the sense of genetic recombination in meiosis.
6. Since each of the parent cell’s chromosomes were replicated during interphase, there are two copies of each chromosome in the cell during prophase. Once the chromatin has condensed into individual chromosomes, the genetically-identical chromosomes come together to form an “X” shape, called sister chromatids .

State the level of organization of euglena onion bulb and blood
Answer:
The correct answer is -
Euglena - single-cell organism
Onion bulb - organ
Blood - tissue (connective tissue)
Explanation:
The level of organization of an organ, or organism could be cellular level, tissue level, the organ level, organ system, or a complete organism. These levels are formed by assembling the lower level of the organization.
Euglena is a single-cell eukaryotic organism found in freshwater. These organisms have a very simple level of an organism which is cellular level. The onion bulb is the organ of the onion plant composed of shortened, compressed, underground stems (tissue) that are an organ-level organization.
The blood is considered as connective tissue due to the blood cells present in the matrix called plasm thus, blood is connective tissue.
