Answer:
The correct answer is: D
Explanation:
(a) This process does not occur during glycolysis, it occurs after glycolysis since pyruvate is generally accepted to be the last product of glycolysis
(b) Phosphofructokinase does not produce two molecules of glyceraldehyde 3-phosphate but rather produces of one molecule of glyceraldehyde 3-phosphate and dihydroxyacetone phosphate
(c) During anaerobic conditions in mammals, pyruvate is converted to lactate by the enzyme lactate dehydrogenase. It can actually cause the accumulation of lactic acid/lactate in the muscle which causes muscle fatigue but does not cause buildup of pyruvate in the cytosol.
(d) In the fate of pyruvate, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH in the mitochondrial matrix. The acetyl-coA produced thereof serves as a precursor for the citric acid cycle.

Students in a science class visited four local ecosystems. The students observed the species present in each ecosystem and recorded their observations in the table.
Based on these observations, which ecosystem is likely to be the least sustainable?
A.Ecosystem 1, because it has the fewest species
B.Ecosystem 2, because it includes both aquatic and terrestrial species
C.Ecosystem 3, because it has few predators
D.Ecosystem 4, because it supports many animals
the answer is A
this is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem
This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.
What is Ecosystem?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity.
Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change in the temperature of an ecosystem will often affect what plants will grow there, for instance.
Therefore, This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.

A local ecosystem includes a variety of grasses that grow on spongy soil. In spring, heavy rainfall and melted snow cover the soil in a few inches
of water. The ecosystem dries up by late summer. What term BEST describes this ecosystem?
A. pond
B. estuary
C. wetland
D. stream bed
Answer:
The correct answer is C. Wetland.
Explanation:
A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.
Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.

Explanation:
The growth of bacteria can be observed as the bacteria grows very rapidly and fast by the process of asexual reproduction. They continuously multiplied and in very short period of time they divided from one to thousands.
What is asexual reproduction?Asexual reproduction is defined as the process of reproduction in which only a single parent is involved. Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.

Photosynthesis/CR definition
Answer:
Photosynthesis is the process in which green plants and some other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Cellular Respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. The following list includes examples of factors that contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Which of the following are consequences of dead zones?
a. Economic losses for fisher's
b. Death or aquatic organism that cannot escape
c. Policies to promote no-till agriculture
d. Construction of wetlands to absorb nutrients
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Answer:
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Explanation:
Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.
These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)
As the algae population feed on the available resources in the water they exhausted this,and later die.
When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available for survival of organisms.
This is reversible if the process if europhication or other causes is eliminated

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Answer:
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
Explanation:
Photosynthesis is the means by which green plants produce their foods by the use of sunlight, chlorophyll and carbon dioxide.
During the day, the grape make use of the process, photosynthesis, to get its sufficient food, thus the reason for the slight shrink. But at night, it respire well and new cells are produced. So that its size increase a bit.

White blood cells called B cells produce proteins that can be used for the treatment of certain illnesses. However, these B cells do not live for very long on their own. To keep the B cells growing for a long time in laboratories, scientists fuse the B cells with cancer cells (fused B-cancer cells) that do grow for a very long time. The particular cancer cells used for the fusion are treated with chemicals that make them unable to produce the nitrogenous bases adenine and guanine, but the B cells with which they are fused do produce these nitrogenous bases. The scientists grow the large fused B-cancer cells in a growth medium that contains necessary nutrients for the cells and includes a source of carbon.
(a) Describe the role of carbon in biological systems.
(b) The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
(c) Make a claim about the most immediate effect on the fused B-cancer cells if the fused cells are transferred to a growth medium that lacks a source of nitrogen.

Explanation:
You are performing an experiment with Primase, using a specific DNA template. In this experiment, you provide NTPs (ATP, UTP, CTP, GTP) which contained only one radioactive phosphate group, in the alpha-phosphate position (the alpha- phosphate is the one attached to the sugar. the other phosphates are beta and gamma). After RNA synthesis occurs, you separate the resultant RNA strand any of the NTPs that have not been incorporated into the RNA, and measure the radioactivity of the newly synthesized RNA.A) In this experiment, would you expect the newly synthesized RNA be radioactive? Explain why.B) If you forgot to add CTP when you did the experiment, would the resulting RNA be radioactive?C) If you did the experiment, with all the NTPs provided, but only the beta phosphate was radioactive for each of the NTPs, would radioactivity be found in the RNA? Explain why.D) If you did the experiment, with all the required NTPs, but only the ATP was radiolabelled Would radioactivity be found in the RNA? Explain why.
Answer:
(a). Yes.
(b). RNA becomes Radioactive.
(c). No.
(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.
Explanation:
So, let us do right into the explanation behind the answers to the questions asked.
(a). The answer to this part of the question is "Yes" because in creating or in the formation of the glycosidic bond, all the alpha phosphate group were taken into consideration that is they were all used, thus making the newly synthesized RNA to be radioactive.
(b). The RNA becomes Radioactive is the answer to this part of this question because CTP is needed in the experiment.
(c). The answer to this part (c) of this question is ''No'' because the only thing that takes part in bonding is the alpha phosphate.
(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.
