Answer:
Blood is a colloid which mainly contains red and white blood-cells, lymphocytes and plasma.
Explanation:
Believe it or not but blood is considered an organ. That’s because it contains a collection of different types of cells suspended in a liquid, the plasma.
The most obvious type of cell is the red blood cell (erythrocytes), which provides the red color to the blood and more importantly contains haemoglobin, an iron holding protein that binds oxygen or carbon dioxide. This way these gases are transported throughout the body. Oxygen towards the tissues, carbon dioxide outward of course.
Another very important blood cell type are the white ones (leukocytes). Without going into much detail (a lot of different subtypes exist) the white blood cells are responsible for one’s immunity. Some of these cells called macrophages like to swallow stuff that’s not supposed to be in your blood.
A third important type of cell, the smallest ones, are the trombocytes or platelets. The make sure you blood coagulates when you are wounded. Without them you would bleed to death.
Besides these cells a lot of different molecules or ions are dissolved or suspended in the plasma : proteins of which a lot of albumin, vitamins, minerals. The steady bloodstream makes sure every cell in your body is provided with the nutrients it needs.
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.

6. Which of these BEST describes our current understanding about how species evolve over time?
A) As organisms use certain traits more frequently, each organism evolves over time.
B) Populations of organisms evolve rapidly due to genetic changes brought about by random mating patterns.
C) Traits that result in a greater number of mutations occur more frequently, causing the population to evolve.
D) Populations evolve as natural selection results in a change in the frequency of alleles within the population over time.
7) A change in a sequence of DNA bases in a bacterial cell has resulted in a mutation. This mutation has increased the ability of the bacteria to break down and digest organic molecules in the environment. Bacteria with this mutation are better able to find and utilize food sources. According to the theory of natural selection, what is MOST likely to occur in future generations of this bacteria?
A) The relative frequency of the mutation will increase as time passes.
B) Because the mutation has changed the DNA of the bacteria, a new species will be formed.
C) Because the mutation is abnormal, the mutation will become more rare with every passing generation.
D) Bacteria with the mutation will increase in number until the food supply is exhausted, causing the bacteria to become extinct.

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 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 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.

C Cold Front
D Occluded Front
Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
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.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.
What is a basic characteristic of all living cells
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).
