What happens during S phase?
O A. Chromosomes are duplicated.
O B. DNA separates into two nuclei.
O C. The cell splits in two.
O D. Cytoplasm is manufactured.
Answer: A. Chromosomes are duplicated.
Explanation: This is the correct answer on the quiz.
Chromosomes are duplicated in S phase. Therefore, option (A) is correct.
What do you mean by S phase?
Between G1 phase and G2 phase, DNA replication takes place during S phase of the cell cycle. The processes that take place during S-phase are tightly controlled and highly conserved.
The cell replicates its genetic material entirely during the S phase of DNA synthesis; At the end of S phase, a normal diploid somatic cell with a DNA complement of 2N acquires a DNA complement of 4N.
DNA synthesis or replication occurs during the S phase of the cell cycle, which occurs prior to the interphase. Before entering mitosis or meiosis, the cell's genetic material is replicated in this manner, leaving enough DNA for daughter cells to divide.

Which of the following does NOT secrete hormones?
A. Ovaries
B. Skin
C. Adrenals
D. Pancreas
Answer:
skin acts as a protective barrier, therefore it does not secrete hormones
Skin does not secrete hormones. Thus, the correct option is B.
What are Hormones?Hormones may be defined as chemical substances that are produced by the organ system of an organism and transported at the site of action via the bloodstream. Hormones act as messenger molecules in the body.
Skin acts as the primary or first line of defense for the immune system. It does not secrete any hormones. It plays an important role in innate immunity. Ovaries are responsible for the secretion of hormones like estrogen and progesterone in females and regulate all the prospective consequences in the body of females.
The adrenal gland secretes hormones like cortisol and aldosterone which are steroid hormones. Such hormones are important in regulating metabolism, inflammation, immune functions, etc. The Pancreas secretes insulin and glucagon which play an active role in regulating the level of glucose in the blood.
Therefore, the skin does not secrete hormones. Thus, the correct option is B.

pls make me brainliest
Explanation:
1. X-ray type electromagnetic radiation has higher energy than visible light and can pass through the human body.
2. Spectroscopy can provide composition and temperature information about objects in space.
3. Visible light is electromagnetic radiation with wavelengths between 380 nm and 700 nm.
4. Radio waves and ultraviolet light are examples of non-visible light.
5. When the emission line of helium from the galaxy is red-shifted as the galaxy is moving away from the viewer
The correct options for 1, 2, 3, 4 and 5 are A, (C and D), D, B and A respectively.
X-rays are valuable in medical imaging and other uses because they have more energy than visible light and can penetrate the human body.
By examining the light emitted or absorbed by the object, which forms a characteristic spectral pattern, spectroscopy can provide details about the composition and temperature of objects in space.
The human eye can perceive visible light because its wavelengths, which range from 380 nanometers to 700 nanometers, fall within this range.
Since their wavelengths lie outside the visible spectrum, radio waves and ultraviolet light are two examples of non visible light.
A galaxy is said to be moving away from the observer when the helium emission line from that galaxy is red-shifted in its spectrum. The Doppler effect, in which light emitted from objects moving away from the observer appears to be skewed toward longer (reddish) wavelengths, is what causes this redshift. This event is an important piece of evidence for the Big Bang theory and the expansion of the universe.
Therefore, the correct options for 1, 2, 3, 4 and 5 are A, (C and D), D, B and A respectively.

Answer:
One is that they migrate to more fertile places.
Second, some animals may die because they can't stand the conditions of treelessness. But some animals can survive. because of adaptation
Explanation:
Removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat
What is Deforestation?Deforestation also known as forest clearance is defined as the removal of forest or stands of trees from land that is converted to non-forest use in which forest land is converted into farms, ranches or urban may involve converting to use. The most concentrated deforestation occurs in tropical rainforests.
It occurs when humans remove or thin forests for timber or use land where trees stand for crops, grazing, extraction such as mining, oil, or gas, or as populations grow and people move. Development takes place in the form of migration.
Wildlife habitats are fragmented due to deforestation, where native species have to live on remaining habitat islands that are surrounded by disturbed land being used for agriculture and other uses.
Thus, removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat

Why are NADH and FADH2 necessities in the electron transport chain?(1 point)
They power the electron transport chain.
They power the electron transport chain.
They remove electrons from the electron transport chain.
They remove electrons from the electron transport chain.
They move down the electron transport chain.
They move down the electron transport chain.
They move electrons to the electron transport chain.
NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.
NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.
Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.
Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.

winter, summer, lighter
winter, summer, darker
Answer:
Its summer, winter, darker.
Explanation:
This is the answer I hope it helps you out.
Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.
What are seasons?A season exists the year that stands determined by particular climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each includes its light, temperature, and weather designs that repeat yearly.
Summer exists the hottest of the four temperate seasons, happening after spring and before autumn. At or centered on the summer solstice, the earlier sunrise and latest sunset happen, daylight hours exist longest and dark hours exist shortest, with day length falling as the season progresses after the solstice.
Winter, the coldest season of the year, between autumn and spring; the name arrives from an old Germanic word that represents “time of water” and guides to the rain and snow of winter in middle and increased latitudes.
Hence, Trees grow more quickly in the summer than in the winter, and the tree rings show up as darker colored bands.

which structures in plant cells build protein molecules under the control of the nucleus?
a) cell walls
b) chloroplasts
c)mitochondria
d) ribosomes
The cell walls, chloroplasts, and mitochondria play important roles in plant cells, they are not directly involved in building protein molecules under the control of the nucleus. D
Ribosomes are the structures in plant cells that build protein molecules under the control of the nucleus.
Ribosomes are tiny, complex molecular machines composed of RNA and protein molecules.
They are involved in the process of protein synthesis, where they facilitate the translation of genetic information from the DNA in the nucleus into functional proteins.
The nucleus of a cell contains the DNA, which serves as the blueprint for building proteins.
However, the actual synthesis of proteins occurs in the cytoplasm, outside the nucleus.
Ribosomes are responsible for this task.
Ribosomes can be found both freely floating in the cytoplasm and attached to the endoplasmic reticulum (ER).
The ones attached to the ER are called rough endoplasmic reticulum (rough ER) due to the presence of ribosomes on their surface.
These ribosomes associated with the rough ER are involved in the synthesis of proteins that are destined for secretion or for integration into the cell membrane.
The process of protein synthesis involves the decoding of the genetic information stored in messenger RNA (mRNA) by ribosomes.
Ribosomes read the mRNA sequence and assemble amino acids into a growing polypeptide chain, forming a functional protein.
Cell walls provide structural support, chloroplasts are responsible for photosynthesis, and mitochondria are involved in cellular respiration. However, the primary site for protein synthesis in plant cells is the ribosomes.
Therefore, the ribosomes (option d) are the structures in plant cells that build protein molecules under the control of the nucleus.
