Plants take in carbon dioxide and release gas
Answer:
yes, but by gas you mean oxygen right?
Explanation:
Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Explanation:
What characteristics of the molecules being transported determines how they will cross the membrane?

D. Charge and structure
What are stem cells? How are embryonic stem cells different from adult stem cells?
Answer:
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated.
Embryonic stem cells are derived during early development at the blastocyst stage and are pluripotent, meaning that they can differentiate into any cell type. In contrast, adult stem cells are rare, undifferentiated cells present in many adult tissues.

11. How has our misguided, or inappropriate, use of antibiotics led to the development of organisms like
MRSA and VRSA?
Answer:
1. use of the wrong antibiotic
2. use of insufficient concentration of the right antibiotic
Explanation:
MRSA means Methicillin-resistant staphylococcus aureus
VRSA means Vancomycin-resistant Staphylococcus aureus
These are resistant forms of the bacteria Staphylococcus aureus to the antibiotics mentioned.
Bacterial resistance to antibiotics occurs when bacteria develop mechanisms that protect them against the effects of previously effective antibiotics.
Misguided and inappropriate use of antibiotics results in resistance, and they mainly occur as a result of two activities:
1. Use of wrong antibiotics: antibiotics are chosen using a microbiological technique called 'sensitivity testing', to determine which antibiotic is effective against a bacterium. However, when antibiotics are taken without proper sensitivity testing, the bacteria develop resistance against such antibiotics.
2. Use of inadequate concentration of the right antibiotic: This involves using less than the minimum inhibitory of minimum bactericidal concentration of an antibiotic against a bacteria. In this case, the organism has ample time to evolve in the presence of the antibiotic, hence the occurrence of resistance.
When farmers want two desirable traits in cows, they often breed individuals that have those traits in the hopes that the offspring will have both desirable traits. What is this practice called?
Variation
Adaptation
Natural selection
Artificial selection
Answer:
artificial selection
Explanation:
When farmers want two desirable traits in cows, they often breed individuals that have those traits in the hopes that the offspring will have both desirable traits. The practice is called Artificial selection.
What is Artificial selection?Artificial selection is the process of identifying desirable qualities in plants and animals and then taking action to strengthen and pass those traits on to succeeding generations.
Artificial selection operates in a similar manner to natural selection, with the exception that in natural selection, these judgments are made by nature without human intervention.
Natural selection, sometimes summed up by the adage "survival of the fittest," is predicated on the following ideas: In the natural world, organisms give birth to more children than they can keep alive and reproduce.
Therefore, When farmers want two desirable traits in cows, they often breed individuals that have those traits in the hopes that the offspring will have both desirable traits. The practice is called Artificial selection.

Describe what happens to the egg during the menstrual cycle on day 14. _______________________
Answer:Ok so A few days before Day 14, your estrogen levels peak and cause a sharp rise in the level of luteinizing hormone (LH). LH causes the mature follicle to burst and release an egg from the ovary, called ovulation, on Day 14.At about day 14 in the menstrual cycle, a sudden surge in luteinizing hormone causes the ovary to release its egg. The egg begins its five-day travel through a narrow, hollow structure called the fallopian tube to the uterus. hope this helps have a nice night ❤️❤️❤️
Explanation:
Answer: Because However, during days 10 to 14, only one of the developing follicles forms a fully mature egg. At about day 14 in the menstrual cycle, a sudden surge in luteinizing hormone causes the ovary to release its egg. The egg begins its five-day travel through a narrow, hollow structure called the fallopian tube to the uterus. The egg travels down the fallopian tubes. If pregnancy doesn't occur, the egg is reabsorbed into the body. Levels of oestrogen and progesterone fall, and the womb lining comes away and leaves the body as a period (the menstrual flow). The time from the release of an egg to the start of a period is around 10 to 16 days.

what is cellular respiration also called
Answer:
Krebs cycle, tricarboxylic acid cycle.
Explanation:
Cellular respiration is what cells do to break up sugars to get energy they can use. ... Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain.
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules[1] or nutrients into adenosine triphosphate (ATP), and then release waste products.[2] The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen,[3] are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.
Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent providing most of the chemical energy is molecular oxygen (O2).[1] The chemical energy stored in ATP (the bond of its third phosphate group to the rest of the molecule can be broken allowing more stable products to form, thereby releasing energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transport of molecules across cell membranes.
Answer:
Alternative Titles: cell respiration, tissue respiration. Discover how cellular respiration transforms your food into energy usable by your cells. Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

4. Which part of the replication process helps reduce the chance for genetic mutation?
a. insertion of RNA primer sequences
b. sealing the gaps between fragments
c. opening multiple origins of replication
d. proofreading new DNA strands
Answer:
D
Explanation:
Key points:
- Cells have a variety of mechanisms to prevent mutations, or permanent changes in DNA sequence.
- During DNA synthesis, most DNA polymerases "check their work," fixing the majority of mispaired bases in a process called proofreading.
- Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process called mismatch repair.
- If DNA gets damaged, it can be repaired by various mechanisms, including chemical reversal, excision repair, and double-stranded break repair.

Why does your vaccination status affect more people than just you?
Answer:
so i belive ur talking about the corona vaccinations so my answer is below! :D
Explanation:
if you get vaccinated, you are helping yourself and other people because it is most likely that you wont get corona if u have a vaccine. When you dont get corona that means that there are less people dying and you will reduce the level of deaths because ur not gonna get corona and give it to someone else. Once you get the vaccine you still have to be protected and wear a mask when you go outside just in case to protect your self and someone elses life. So, thats why ur vaccination status affects more people than just you. :D
also i just realized that you might not be talking about the corona vaccinations and u can be talking about the normal vaccines but the paragraph that i just wrote can be meant for normal vaccines as well :)
Why do you think having such an extensive membranous area is beneficial when performing photosynthesis?
Answer:
Increasing the membrane area also increases the number of ATP and NADPH generating sites
Explanation:
Photosynthesis occurs in the chloroplast, more precisely in the membranes of the thylakoids that form stacks of disks called grana. A mature chloroplast may have 20 to 60 grana. In these membranes, there are photosystems, which are structural units of pigment-protein complexes that convert light energy from the sun into chemical energy stored in ATP and NADPH. A thylakoid may contain thousands of photosystems. In consequence, increasing the membrane area also increases the number of photosystems required for the synthesis of ATP and NADPH.
