is gene paired on endosperm cell?
Answer:
yes
Explanation:
What is the genetic makeup of endosperm?
One sperm fuses with the egg to form a diploid zygote, and the other sperm fuses with two female-gametophyte nuclei (known as polar nuclei) to form the triploid primary-endosperm nucleus. Therefore, the endosperm, which devel- ops from this triploid nucleus, has an unusual genetic composition

what conditions prompt hemoglobin to release oxygen? select the three answers that are correct.
The conditions that prompt hemoglobin to release oxygen are:
Decrease in pH (high acidity)ExerciseUnloading of oxygen from haemoglobinHaemoglobin is the blood protein that is used to carry oxygen in our body and gives blood its red colour. The ability of this protein to carry oxygen depends on some factor. These factors include:
Decreased pH: Upon the production of carbondioxide in the tissue cells, carbonic acid is produced which leads to decrease in pH of the blood. Exercise: During exercise, the temperature of muscle increases secondary to its utilisation. This will cause the release of unloading of oxygen from haemoglobin.Therefore, conditions that prompt hemoglobin to release oxygen are decrease in pH (high acidity) and exercise.

How do the organs in the endocrine system work together?
A. Organs produce hormones that change a child's body into an adult.
B. Organs filter toxins from blood and urine.
C. Organs transport oxygen to different parts of the organism.
D. Organs transmit electrical signals throughout the organism's body.
Answer: The answer is A, organs produce hormones that change a child's body into an adult.
Explanation: The endocrine system is responsible for regulating a range of bodily functions through the release of hormones.
Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function.

Answer:
The disadvantages for both cells are that neither is an accurate representation of the cell themselves, or the processes. The first cell doesn't tell us exactly what phases the cell is currently going through, and the cell doesn't go through is phases through grey arrows either. However, it does tell us what the phases look like, and the process of how the cell goes through them. The disadvantages of the second map is that, it doesn't show what the phases look like, the advantages are that tells us what the phases are and what comes before and after them, while showing how this occurs in a cycle and keeps going until senescense.

if I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result
What is my number and how do you work it out?
The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
(x - 20)² = x² - 20
expand the equation;
x² - 40x + 400 = x² - 20
collect similar terms together;
x² - x² - 40x = -20 - 400
-40x = -420
[tex]x = \frac{420}{40}\\\\ x = 10.5[/tex]
Thus, the value of the unknown number is 10.5.

what is the primary action of antidiuretic hormone?
Answer:
The primary action of the antidiuretic hormone is that it causes collecting ducts in the kidneys to reabsorb more water.
Explanation:
Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.
What is Anti-diuretic hormone (ADH)?Human vasopressin is also called antidiuretic hormone, arginine vasopressin or argipressin. It is defined as the hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus that converts to AVP.
ADH is the hormone that helps constrict blood vessels and helps the kidneys control the amount of water and salt in the body which helps control blood pressure and the amount of urine. This reduces the amount of urine released and the nature of urine becomes hypertonic which is concentrated. Because of this type of action, vasopressin is known as an antidiuretic hormone.
Thus, Human vasopressin is also known as the Anti-diuretic hormone (ADH) causes kidney-collecting ducts to reabsorb more water.

1. Why does the angle of the sun at noon seem to change at different months throughout the year?
2. How does this create seasons?
Answer:
1. The earth orbit is slightly elliptical, and the earth axis is tilted by roughly 23.5° to the orbit. These to factors combine to make the an analemma. But in the winter, When the Earth is on the other side of orbit, the Earth's north pole is tipped away from the Sun, so at noon the sun doesn't get as high.
2. The earth's spin axis is tilted with respect to it's orbital planet. This is what causes the season. When the earth's axis points towards the sun. it is summer for that hemispheres. Midway between these two times in spring and autumn, the spin axis of earth points 90 degrees away from the Sun.

If ATP production is blocked, decreased transport of material across a membrane occurs. Which type of transport would be affected
Answer: Active transport
Explanation:
This transports requires ATP because the material would be going against the gradient (Low to high concentration). Since this is not the "normal" tranportation (High to Low concentration) it therefore needs ATP. Without ATP it cannot do it's transportation.
