Organisms use glucose to store and transport energy.
True
False
Answer:
Glucose and ATP are used for energy by nearly all living things. Glucose is used to store and transport energy, and ATP is used to power life processes inside cells. Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose.
Explanation:
Most organisms use glucose and ATP for energy. ATP powers cells, and glucose stores and transports energy. Photosynthesis converts sunlight into glucose for many autotrophs.
What do organisms use to store and transport energy?All living things use ATP and glucose as energy sources. Energy is stored and transported by glucose, and cellular life functions are powered by ATP. Through the process of photosynthesis, which converts solar light energy into chemical energy that is stored in glucose, many autotrophs produce food.
Glycogen is the name given to this form of glucose that is stored and is composed of several linked glucose molecules. Glycogen is broken down to release glucose into the bloodstream, which is then used as fuel for the cells, when the body needs a sudden surge of energy or when the body isn't obtaining glucose from food.

When does chromatin form into chromosomes?
Answer:
Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus.

Explanation:
Genetic drift in a population affects the gene pool in which of the following ways?
decrease in genetic variation
increase in genetic variation
increased in mutations
decreased in gene flow
Answer:
Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time. ... Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool.
Genetic drift in a population affects the gene pool by decreasing genetic variation.
What is genetic drift?Genetic drift is a mechanism of evolution that occurs due to random fluctuations in the frequency of alleles (alternative forms of a gene) in a population. It refers to the random changes in the frequency of alleles that occur by chance alone, rather than through natural selection or other selective pressures.
Genetic drift is more likely to occur in smaller populations, where chance events can have a greater impact on the frequency of alleles. The effects of genetic drift can result in the loss of certain alleles from a population over time, or the fixation of one allele in a population, meaning that it becomes the only allele present at that particular gene locus.
Two forms of genetic drift are bottleneck effect and founder effect. In the bottleneck effect, a sudden reduction in population size can cause the loss of genetic diversity, while in the founder effect, a small group of individuals colonizes a new area, leading to the establishment of a new population with a limited subset of the genetic diversity present in the original population.

Answer:
Provide an enormous surface area that facilitates absorption.
Explanation:
The villi of the small intestine provides an enormous surface area that facilitates absorption of nutrients from the small intestine. The cells present on the villi are packed full of tiny hair-like structures called microvilli. It performs the same function as villi perform in the small intestine i.e. absorb nutrients. Villi are surrounded with cells that help in the absorption of nutrients from the food that passes through it.

It’s not multiple choice, I need help coming up with two more answers that are true
Answer:
Phosphorylation activation:
1- p53 (transcriptional activator)
2- CDK8-cyclin C (transcriptional inhibitor)
Explanation:
Phosphorylation is a well-studied post-translational modification mediated by a protein called 'kinases' which phosphorylates specific protein substrates. This post-translational modification (phosphorylation) acts as a reversible switch capable of modulating protein function. Phosphorylation at specific amino acid residues (e.g., tyrosine, serine) controls protein function by triggering conformational changes in the phosphorylated protein. For example, P53 is a transcription activator activated by phosphorylation at multiple sites in its N-terminal region. P53 activates transcription of different genes by modulating protein-protein interactions with different substrates (e.g., MDM-2, CBP/p300, TFII). On the other hand, cyclins are proteins that have no enzymatic activity but are able to activate cyclin-dependent kinases (CDKs) by binding to them. CDK8-cyclin C (SRB10-SRB11) is a negative regulator of transcription that is able to inhibit transcription by phosphorylating the carboxy-terminal domain of the largest subunit of RNA polymerase II (Pol II) before the formation of the preinitiation transcriptional complex.
While studying the cells of a newly discovered fungus, you notice that its organelles resemble those of most eukaryotes, but some of their shapes are a little different. Although you're pretty sure you can identify each organelle, you analyze its chemical composition just to make sure. One organelle is shaped like a ball, and it is composed of proteins, membranes, and nucleic acids. That organelle is most likely the
Answer:
nucleus
Explanation:
The organelle would most likely be the nucleus.
The nucleus happens to be a membrane-bound organelle that is somehow round in shape. It houses most of the genetic components of the cell, including proteins and nucleic acids in the form of DNA.
Fungi themselves belong to the eukaryotic category of living organisms and as such, every fungus cell is expected to have a nucleus and other membrane bound organelles such as mitochondrion.
Hence, the organelle would most likely be the nucleus of the fungi cell.

The total number of molecules of ATP produced during glycolysis is ______, which results in a net production of _____ ATP.
Answer:
The answer is "4 and 2 ".
Explanation:
The overall glycolysis ATP number is 4 of one hydroxyl group. In the first part of the glycolysis 2 ATP molecules are used, so that 2 ATP molecules are net gained. 2. In addition, 2 NADH atoms in the glycol are also created. This is why the total ATP molecules produced during metabolism are 4, resulting in a net output of 2 ATP.
