Answer:
Random Assignment
Explanation:
Random Assignment
Is to randomly assign subjects to different treatment groups to reduce the chances of preexisting differences between the subjects having an impact (negative) on the experiment.
An animal that is only a secondary consumer can also be called a HERBIVORE
Answer:
See explanation below.
Explanation:
Mitosis is the duplication of cells in the bodies of plants and animals. All cells can undergo mitosis. Mitosis benefits the body by replacing cells as needed. The skin for example loses a lot of cells. Mitosis is when cells reproduce - and results in an exact copy - to replace the cells that are lost or need to be replaced for other reasons.
Meiosis is the duplication of cells that are not alike. In Mitosis, the duplicate cells are an exact copy, with a full exact copy of the body's DNA. In Meiosis, the new cells are different in that each one has half of the DNA - or half the number of chromosomes. Meiosis allows for the creation of cells that allows for sexual reproduction. Meiosis is the process that creates sperm and eggs. These cells are known as haploid cells - in that other cells are known as diploid, with full DNA and cells that have gone through the meiosis process have half and are known as haploid cells.

The appropriate answer is d. Dead plants in a swampy environment is the perfect environment for the beginning of the coal forming process. Over time layers pile up in this anaerobic environment. The plant or organic material gets buried overtime by dirt or rocks. Millions of years of burial will expose the matter to heat and pressure and will eventually lead to the formation of coal and other petroleum products.
Answers:
Hormones are chemical messengers....
Endocrine glands secrete hormones...
The pituitary gland plays...
is produced by the adrenal glands...
the gland will produce fewer amounts of the hormone...
produce chemicals called paracrine factors...
blood is called the thyroid.
Steroid hormones are synthesized from cholesterol, while nonsteroid hormones are synthesized from modified amino acids and small peptides. Non-steroid hormones are not lipid-soluble and therefore they need to bind to a receptor on a cell membrane; while steroid hormones can diffuse through the cell membrane.
Explanation:
Hormones are signaling molecules synthesized by glands. The endocrine glands include the adrenal glands, pineal gland, thyroid gland, parathyroid gland, pituitary gland, ovaries, testes, pancreas and hypothalamus. The pituitary gland is an endocrine gland that secretes hormones capable of stimulating the adrenal glands in order to produce steroid hormones. Hormone levels are often modulated by negative feedback, by which high-hormone levels reduce their own production. Paracrine factors (also known as growth and differentiation factors) are proteins that can diffuse across small distances in order to induce responses in neighboring cells. The thyroid gland secretes hormones involved in regulating metabolism and growth. Moreover, the thyroid gland also secretes calcitonin that regulates calcium levels in the blood.
