What
type of mutation causes this the sequence AGTATA to become AGTATTA
Answers
Answer:
Insertion
Explanation:
Mutation is generally referred to as any change or alteration that occurs to the nucleotide sequence of a gene. There are several types of mutation depending on how it occurs. The types of mutations are; substitution, insertion, deletion, etc.
Insertion mutation is a type of mutation in which one or more nucleotide base is added a sequence. This is the case in this question about an original sequence that reads: AGTATA. We then have the mutated sequence as follows: AGTATTA
Notice that, nucleotide "T" has been added in between T and A. Hence, a type of INSERTION mutation.

Explain why mining has such a large impact on the environment.
Answers
Answer:
Mining has a large impact on the environment because minerals are contained within the Earth. Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.

The brachial plexus is associated with which of the following?
A. Innervation of the upper limbs
B.Innervation of the lower limbs
C.Axillary nerve is a terminal branch
D. A and B are correct
E. A and Care correct
Answers
Answer:
innervation of the upper limbs
The brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.
What is the brachial plexus?It is responsible for providing the motor (muscle), sensory and sympathetic innervation of the upper limb.
Through it, the spinal cord is connected with all the peripheral nerves of the upper limbs and all the sensorimotor information of these segments is also transmitted.
Therefore, we can conclude that the brachial plexus is a nerve network located at the base of the neck and the axillary fossa associated with sensory and motor innervation for the entire upper limb.

Which of the following statements about hormones is incorrect? a) Glands that produce them are ductless glands. b) They are produced only by organs called endocrine organs. c) Some are water soluble and some are not. d) They often maintain steady-state conditions. e) They may turn genes off or on
Answers
Answer:
b) They are produced only by organs called endocrine organs.
Explanation:
Hypothalamus can be defined as a small portion of the mammalian brain responsible for the secretion of hormones through the stimulation of the pituitary gland.
It is located between the midbrain and the thalamus. Also, hypothalamus is the most inferior portion in the diencephalon of the forebrain.
Basically, hypothalamus is the most important portion of the brain in vertebrates that controls various bodily functions.
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
The following statements about hormones are correct;
I. Glands saddled with the responsibility of producing hormones are ductless glands i.e directly secreting hormones into the bloodstream.
II. Hormones are either soluble in water or insoluble in water.
III. Hormones are often responsible for maintaining steady-state conditions in the body of a living organism through homeostasis.
IV. Hormones are typically able to turn genes off or on.

Answers
Answer:
- Ethylene
- Thigmotropism a response to touch
Explanation:
1. Plant hormones or phytohormones are of different types with varying functions. They include; auxins, gibberellins, ethylene, abssicic acid etc. Specifically, ETHYLENE or ETHENE is responsible for hastening the ripening process in fruits of plants.
2. Tropism refers to the response of an organisms to stimuli. There are different types of tropism depending on the stimuli source.

Answer:
False
Explanation:
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

What is the most abundant plant hormone and where is it found in the plant?
Answers
Answer:
Indole-3 acetic acid
Explanation:
IAA causes cell wall extension by activating the proton pump, which keeps the cell wall acidic at a pH of around 4. The cell wall pressure is reduced in these conditions, and water enters the cell, resulting in an increase in cell volume. As the cell grows in size, new cell wall material is required to keep the wall stable. Auxin IAA is a naturally occurring substance. It also promotes cell enlargements, cell division in the vascular cambium, root initiation enlargement, cell division in VA.
IAA can be found in the seeds of many plants, especially legumes like peas and broad beans.
