Describe the life cycle
of mosquito and cockroach
Answer:
the cockroach life cycle is comprised of three developmental phases, the egg, nymph and the adult stage. Most cockroaches are oviparous — their young grow in eggs outside of the mother's body. ... These nymphs will feed and go through a series of moultings over a period of one year as they develop into adults
The description of life cycle of mosquito and cockroach is that the cockroach life cycle has been comprised of three developmental phases, the egg, nymph and the adult stage. Most cockroaches are oviparous it means they lay eggs and their young ones grow in the eggs outside the mother's body. These nymphs will be feed and go through a series of the moultings over a period of one year as they develop into adults.
What is oviparous?Oviparous is the animals that lay eggs as their young ones and Most cockroaches are oviparous it means they lay eggs and their young ones grow in the eggs outside the mother's body. These nymphs will be feed and go through a series of the moultings over a period of one year as they develop into adults.
Genetic mutation, crossing over during meiosis, polypoidy is an example of a cause of natural variation to the mechanism of natural selection. Variation shown in many ways such as physical appearance, metabolism, reproduction, fertility behavior, learning and mental ability, such variation is called as natural variation.
Therefore, The description of life cycle of mosquito and cockroach is that the cockroach life cycle has been comprised of three developmental phases, the egg, nymph and the adult stage. Most cockroaches are oviparous it means they lay eggs and their young ones grow in the eggs outside the mother's body.

Question 3
Some globular proteins are water soluble, while all fibrous/membrane proteins are water insoluble.
Which of the following statements BEST explains the reason for these differences?
A
Fibrous proteins have a large number of hydrogen bonds between the amino acids in the polypeptide chains that stabilize their structures, preventing solubility in water. The globular proteins that are water-soluble do not have as many hydrogen bonds between the amino acids in their peptide chains, allowing water solubility.
B
Fibrous proteins are configured in a way that exposes the polar side chains of the amino acids on the surface of the protein, preventing solubility in water. The globular proteins that are water soluble have nonpolar side chains on the surface of the protein, allowing water solubility.
C
Some globular proteins are configured in a way that exposes the polar groups of the amino acids on the surface of the protein, allowing water solubility. Fibrous proteins have nonpolar side chains on the surface of the protein, preventing water solubility.
D
Some globular proteins are composed of more than one polypeptide chain that weakly interacts with one another, allowing water solubility. Fibrous proteins are composed of only one polypeptide chain that tightly folds, preventing water solubility.
Globular proteins are spherical proteins which are water soluble and forms colloid in water.
The best statement which will explain the reason for difference in globular protein and fibrous proteins is statement C.
C. Some globular proteins are configured in a way that exposes the polar groups of the amino acids in the surface of the protein, allowing water solubility.
Fibrous proteins have non polar side chains on the surface of the proteins, preventing water solubility.
Globular proteins are water soluble. Fibrous proteins are not soluble in water.
Amino acids chain prevents folding up so that the chain is not broken and it remains in elongated form. The correct answer is C.

Explanation:
Some causes of cancer include smoking, obesity, and lack of nutrition. Cancer is diagnosed using a biopsy. A biopsy is a procedure in which the doctor removes a sample of tissue. A pathologist looks at the tissue under a microscope and runs other tests to see if the tissue is cancer. Some treatments for cancer include Chemotherapy, surgery, Radiation therapy, and bone marrow transplant.
The most common cause of arthritis is usually if your family has a history of arhritis. It is usually diagnosed with an x-ray or a blood test. Treatment includes Painkillers, physical therapy, and exercise.
A poison placed on the tips of darts by natives of the Amazon rainforest paralyzes prey such as small mammals. Which of the prey's cells are most likely affected by the poison?
muscle cells
epithelial cells
red blood cells
white blood cells
Muscle Cells, this is the only one that would cause paralyzation
The poison placed by natives of the Amazon rainforest on the tips of darts affect the muscle cells of the prey. Therefore, the correct statement is option A.
What are the functions of muscle cells?The poison placed by natives of the Amazon rainforest on the tips of darts affect the muscle cells of the prey. Muscle cells are responsible for the movement, i.e., contracting and relaxing. The poison also paralyze muscle cells of the prey, which causes them to be unable to move.
Poison can interfere with the muscle cells of prey. The poison can bind to the receptors on the surface of the muscle cells, thereby, blocking the neurotransmitters responsible for sending signals to the muscles to contract.
The poison can also interfere with the cellular processes responsible for generating the energy without which, the muscle cells are not be able to contract. Poison have a direct impact on the ability to move, making the prey easier to capture.
Therefore, the poison affect the muscle cells of prey.

What is classification? Why is it necessary to classify animals and plants?
Answer:
Explanation:
Scientists use Taxonomy, the science of classifying living things, in order to make sense of biodiversity and how living things are related. For example, the classification of species is important in light of a changing environment because it helps scientists keep track of endangered species and what new species were formed because of the environmental change.
The following chart lists taxonomy classifications for seven organisms. Some have just one classification, while others have a subclassification. Which four classifications best match the classifications of your fossils? Research the classifications if you don’t know their characteristics.
Classification
Organism 1 Brachiopoda
Organism 2 Mollusca, Gastropoda
Organism 3 Arthropoda, Trilobita
Organism 4 Chordata, Actinopterygii
Organism 5 Pteridophyta
Organism 6 Nematoda
Organism 7 Ascomycota
Now complete the following table to explain your reasoning for the classification of your fossils
The characteristic features of the fossil will determine to which taxonomic classification it will belong to.
What is taxonomic classification?Taxonomic classification is the organisation of organisms based on similarities in their structure and function.
