Cytokinesis
Describe the purpose of mitosis.
Answer:
Mitosis is a type of cell division which produces two genetically similar daughter cells. This is involved in the cells of growth of somatic cells in an organism which has to to be produced with the same genetic material. It is also involved in the asexual mode of reproduction as it produces clones with the same genetic material such as in angiosperms.
Mitosis is divided into two phases- karyokinesis and cytokinesis where karyokinesis is divided into 4 stages which can be easily marked as:
Prophase- chromatin condensation, nuclear envelope disappears. Prometaphase- chromatin condenses to form a packaged structure called chromosomes. Metaphase- chromosomes align at the equatorial plate of the cell, chromosomes highly condensed. Anaphase- chromosomes start separating, each chromatid moves towards the opposite pole of the cell. Telophase - cytokinesis begins, nuclear envelope reappears. Cytokinesis- cell division by the appearance of cell furrow in animal cells and cell plate in plant cells.What is a basic characteristic of all living cells

Blue whales and ferrets separate at the superorder level in biology.
Blue whales and ferrets separate at the superorder level, which happened between 85 and 105 million years ago. The exact relationships among the superorders are still not entirely clear, but they have distinct evolutionary paths.
Which headline would be an example of genetic engineering?
A.) Mrs. O'Hara Gives Birth to Fourth Redhead
B.)Farmer Brown's Pigs: Best Quality Ham for the money
C.) Gene Added to Liver Improves Clotting Time
D.) Bacteria Make Human Insulin
Answer:
The correct answer is option D, Bacteria Make Human Insulin
Explanation:
Through the recombinant technology of genetic engineering, DNA of one organism can be transferred into the DNA of other organism. In a bacteria, the genes can be modified to produce human insulin. The gene for human insulin is chemically joined to the plasmid of bacterial DNA. Thus whenever the bacteria replicates its DNA, it also replicates the gene for human insulin thereby producing multiple sets of synthetic human insulin.

Which statements accurately describe matter? Check all that apply. Only living things are made up of matter. Matter is made up of tiny particles called atoms. Atoms were discovered in the twenty-first century. Atoms cannot be divided. A single atom can be seen only with a standard microscope.
The right options are;
Matter is made up of tiny particles called atoms, and atoms cannot be divided.
A matter is any object that has mass and occupies space (volume). All matter are made up of tiny particles known as atoms. Atoms are composed of interacting subatomic particles which are; electrons, protons, and neutrons. Matter exists in various states such as solid, liquid, and gas.
Answer:
Matter is made up of tiny particles called atoms.
Atoms cannot be divided.
Matter is defined as anything that has mass and occupies space which could be a plant or animal.
Matter is however made up of smaller/tiny particles called Atom. Matter was discovered in the seventeenth century and not in the twenty first century.
Atom however cannot be divided into smaller parts and is regarded as the smallest unit of matter although it contains some sub-atomic particles such as proton and neutron.
It can however be viewed only with an electron microscope as it is too small to be viewed by a light or standard microscope.

Describe the mass and surface temperature of the main sequence stars.
Answer:
Mass of main sequence star - 10 to 200 times of mass of sun
Temperature of main sequence star - 15-18 million kelvin
Explanation:
Majority of stars in the universe are main sequence stars. These stars consists of helium in their cores. Mass of main sequence stars can be as low as one tenth of mass of sun and can be as high as 150 to 200 times the mass of sun. The age of a star depends on its mass. Thus more massive a star is more is its life. The temperature of star is high enough to fuse the hydrogen with in them to form helium atom. Their temperature can be as high as 15-18 million kelvin.

Which BEST explains why people see bananas as yellow?
People can see bananas as yellow because the yellow color is reflected on the surface of the bananas.
What is the reflection of light?It is referred to as light reflection when a light ray hits a polished, smooth surface and bounces back. The incident light rays hit the surface and are reflected off of it. The beam that returns is referred to as the reflected ray.
Reflected light from a mirror or a still body of water is a common example of reflection, but reflection also impacts other kinds of waves besides light waves. Other waves that can reflect include seismic waves, sound waves, water waves, and particle waves.
All colors are absorbed by the surface of the banana, and only the yellow color is reflected. Therefore, people can see bananas as yellow.

in humans , the allele for long eyelashes is dominant (L) and the allele for short eyelashes is recessive (l). a female who is homozygous for long eyelashes and a male with short eyelashes have a child. identify the phenotype and genotype ratio of the offspring.
When a homozygous female with long eyelashes (LL) and a male with short eyelashes (ll) have children, all offspring will have long eyelashes with a genotype of Ll, leading to a phenotype ratio of 100% long eyelashes and a genotype ratio of 100% heterozygous (Ll).
In humans, the allele for long eyelashes is dominant (L) and the allele for short eyelashes is recessive (l). A female who is homozygous for long eyelashes (LL) and a male with short eyelashes (ll) will have children. All of the offspring will have one dominant allele for long eyelashes from the mother and one recessive allele for short eyelashes from the father, resulting in a genotype of Ll for each child. Since the long eyelash allele is dominant, all of the children will exhibit the phenotype of long eyelashes. Therefore, the phenotype ratio of the offspring will be 100% long eyelashes, and the genotype ratio will be 100% heterozyous (Ll).

The image shown is an artist's drawing of a nerve cell. The overall shape and structure of a nerve cell is unlike most other types of cells. Which particular function of nerve cells is facilitated by the unique shape of the cell? A) communication B) digestion C) metabolism D) transportation
The correct answer is option A which is communication.
Explanation:Nerve cells have a different structure from other types of body cells due to a different function.
The function of the nerve cell is to communicate the nerve signals in the nervous system from the receptor to the brain and from the brain to the effector.
The nerve cell has a cell body and an extended fiber type area known as the axon.
This specific structure is suitable for the transport of nerve impulse from one end to another which is for the communication between two nerve cells.
