Answer:
2048
Explanation:
Since DNA is formed from a 4 letter of bases: A, T, G, C (adenine, thymine, guanine, and cytosine) therefore we have 4^5
Since the base sequence is the same as the reverse,
The number of DNA of sequence of 6 bases=4^6= 4096
Since, the reverse is the same as the forward sequence then the answer is divided by 2 =4096/2 = 2048

Answer:
False, it is only represented by one class: Crinoidea (sea lilies).
Explanation:
Echinoderms (phylum Echinodermata) are marine organisms that comprises more than 6,000 species. These animals are deuterostomes that are differentiated to have an ambulacral vascular system and a pentameric symmetry. Echinoderms are divided in the following classes: 1- Ophiuroidea (snake stars), 2-Asteroidea (sea stars), 3-Crinoidea (sea lilies), 4-Holothuroidea (sea cucumbers) and 5-Echinoidea (sea urchins), which can be easily distinguished by anatomical and ecological characteristics.

g you are given three bacterial cultures: Pseudomonas aeruginosa, Shigella sonnei & Escherichia coli and you carry out a Triple Sugar Iron (TSI) assay for each 1. The tube for P. aeruginosa shows a pink butt, pink slant with no gaps or breaks in the medium and no black precipitate 2. The tube for S. sonnei shows a yellow butt, pink slant with no gaps or breaks in the medium and no black precipitate 3. The tube for E. coli shows a yellow butt, yellow slant with no gaps or breaks in the medium and no black precipitate Which of these organism can reduce glucose but not lactose and/or sucrose?
Answer:
Test Tube 2 (S. sonnei)
Explanation:
Triple sugar iron agar test is the microbiological assay used to test the fermentation reaction performed by the bacteria. The fermentation process differs based on substrate and the acids formed as a byproduct.
The test is based on the byproduct formed as a result of fermentation. The test tube contains 1% lactose, 1% sucrose and 0.1 % glucose, ferrous sulphate, phenol red pH indicator.
When the bacteria ferment any of the three sugar, the medium turns yellow.
In test tube 1- The tube shows pink slant, pink butt and no black precipitate which indicates that no fermentation took.
In test tube 2- the tube shows pink slant, yellow butt and no black precipitate due to fermentation of Glucose only due to alkali acid reaction.
In test tube 3- the tube shows yellow slant and yellow butt which shows that glucose and either lactose or sucrose has been fermented.
Thus, test tube 2 (S. sonnei) is the correct answer.

How would you describe the movement of the sun over 30 minutes?
Answer:
The Earth rotates from the west to east. The Sun does not rotate around the Earth, in Thirty minutes. the sun would appear to be in a different part of the sky, and that is because of the Earth's rotation.
Explanation:
Answer:
The sun is seen in a different part of the sky, but this is due to the rotation of the Earth. The intensity of light and heat changes as the Earth rotates. The speed of the sun changes the angle of the sky in 30 minutes, it is always moving from east to west, so in 30 minutes it will move further west, no matter what time you experiment.

100 POINTS. What is the difference between a learned behavior and an inherited behavior? Give one example of each. Please will mark brainliest.
Answer:
An Inherited behavior is a behavior received from the parents through genetics such as long legs for speed while a learned behavior is a behavior in wich an animal has to learn by itself by looking at past experiences such as baby ducks learning how there mother duck avoids danger.
Explanation:
Answer:
A learned behavior is more a behavior that is learned from experience of an organism. An example is imprinting, in which a young animal comes to recognize (another animal, person, or thing) as a parent or other object of habitual trust.
An inherited behavior is one that is innate, something that is bestowed upon an organism at birth. An example is animals starting to instinctually prepare for winter as the weather turns cold during the fall.

The size of the iris and pupil can change size. If you walked from a bright room into a dark room, what would happen to the size of the iris and pupil?
Group of answer choices
the iris and pupil would not change size
the iris would get smaller, the pupil would get bigger.
the iris would get smaller, the pupil would get smaller
the iris would get bigger, the pupil would get smaller
the iris would get bigger, the pupil would get bigger
The correct answer is B. The iris would get smaller, the pupil would get bigger.
Explanation
The iris is the name by which the colored part of the eye is known, it is located between the cornea and the lens. In the central part of the iris, there is a round opening known as the pupil. The relationship between these two parts of the eye is very important to sight because between them they control the amount of light that enters the eye. This occurs when the eye is exposed to a high amount of light, the iris muscles make the pupil smaller and the iris larger, limiting light entry into the eye. When the eye is exposed to low amounts of light or darkness, the iris becomes smaller and the pupil enlarges, allowing more light to enter. According to the above, the correct answer is B. the iris would get smaller, the pupil would get bigger. Because it describes the behavior of the iris and the pupil when going from a bright room to a dark room.

Insulin is a hormone that travels through the blood and helps regulate blood sugar levels. Which best describes how insulin travels in the blood?
in the plasma
in the platelets
attached to the white blood cells
attached to the red blood cells
Answer:
A:in the plasma
Explanation:
Insulin regulates blood sugar levels and it travels in the plasma. Therefore option A is correct.
What is insulin?Insulin is a hormone that is released by β-cells of the pancreas. It controls the amount of glucose in our bodies. It converts glucose into glycogen and then this glycogen is stored in the liver, and whenever the glucose level reduces in the blood, then this stored glycogen is converted into glucose. It also helps in breaking fat and protein for energy.
Insulin is a very important hormone for the regulation of glucose in the blood. A deficiency of insulin occurs when the immune system attacks islets and it causes diabetes, in this disease blood sugar level increases
.
Insulin flows in the blood through plasma. Therefore, option A is correct.
