To reproduce, female elephants produce eggs and male elephants produce sperm. Offspring are produced by the fusion of an egg with a sperm cell. Which statement is true about the offspring? A. The offspring are genetically distinct from the parents because the egg and sperm are both diploid. B. The offspring are genetically identical to the parents because they are produced by sexual reproduction. C. The offspring are genetically distinct from the parents because they are produced by sexual reproduction. D. The offspring are genetically identical to the parents because the egg and sperm are both diploid.
The right answer is C. The offspring are genetically distinct ... by sexual reproduction.
Sexual reproduction, as opposed to asexual reproduction, indicates that the propagation of a species involves male and female gametes. It is the main method of reproduction of multicellular organisms.
In the first stage of sexual reproduction, meiosis, the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During fertilization ("fertilization"), haploid gametes come together to form a diploid zygote and restore the initial number of chromosomes (2n).
Answer: C. The offspring are genetically distinct from the parents because they are produced by sexual reproduction.
Explanation: Sexual reproduction occurs through the fusion between an egg and a sperm cell. Each of these cells has a single set of chromosomes and thus are haploid. As a result, the offspring will be a diploid organism with half of its genetic material coming from the mother and half from the father.
Because the offspring is a combination of the parental genetic information, its own genetic setup will be thus unique compared with that of each parent.
The type of reproduction in which the offspring is identical to the parent is called asexual reproduction. Here, one organism produces a genetic copy of itself, without exchanging genetic information with another organism through sex.

This product of glycolysis, ____ is degrades in the final stages of aerobic pathways
The answer to your question is,
pyruvate
-Mabel <3
Final answer:
The product of glycolysis degraded in aerobic pathways is pyruvate, which is converted into acetyl CoA and further oxidized in the Krebs cycle to produce ATP, NADH, and FADH2.
Explanation:
The product of glycolysis that is degraded in the final stages of aerobic pathways is pyruvate. In aerobic conditions, pyruvate enters the mitochondria to be fully oxidized. This multi-step process includes the conversion of pyruvate to acetyl CoA, which is subsequently utilized in the Krebs cycle for further energy production. The complete oxidation of glucose during aerobic respiration involves both substrate-level phosphorylation and oxidative phosphorylation, resulting in the formation of ATP, GTP, and the reduction of NAD+ and FAD to produce NADH and FADH₂, respectively. These reduced coenzymes are essential for the mitochondrial electron transport chain that ultimately generates a significant amount of ATP.

The glycogen in meat and poultry is a significant source of calories in our diet. question 2 options:
The statement is false.
Meat is mostly the muscle tissue of an animal composed of water (about 75%), protein, and fat. The glycogen (multibranched polysaccharide of glucose) is a sugar stored in muscle (reserve molecule of the muscle) and its breakdown produces enough energy (in a form of ATP) to contract the muscles. It also produces lactic acid. When there is no blood flow (when muscles become meat) to carry the lactic acid away, the acid builds up in the muscle tissue.
"The statement ""The glycogen in meat and poultry is a significant source of calories in our diet"" is false.
Glycogen is a storage form of glucose found in the muscles and liver of animals, including meat and poultry. However, after an animal is slaughtered, the glycogen stores are quickly depleted due to the conversion of glycogen to lactic acid, which is a part of the post-mortem process that affects the tenderness and pH of the meat. Therefore, the amount of glycogen present in cooked meat and poultry is minimal and does not contribute significantly to the caloric intake in a typical human diet. The primary sources of calories in meat and poultry are the proteins and fats they contain.
To summarize:
- Glycogen is present in the muscles of animals before slaughter.
- Post-mortem, glycogen is converted to lactic acid, reducing its presence in the meat.
- The remaining glycogen in cooked meat and poultry is not a significant source of calories.
- Proteins and fats are the main calorie contributors in meat and poultry.
The correct statement reflecting the role of glycogen in meat and poultry in our diet would be: ""The glycogen in meat and poultry is not a significant source of calories in our diet, as it is present in minimal amounts due to post-mortem changes."""

Which substance is produced as a by-product of both glycolysis and aerobic respiration? A. NADH B. acetyl CoA C. ATP D. glucose
The correct answer is option C, that is, ATP.
Glycolysis refers to the dissociation of sugar, generally the glucose into more convenient components in order to generate energy. The net end components of glycolysis are two NADH, two pyruvate, and two molecules of ATP.
The cells going through the procedure of aerobic respiration generate six molecules of carbon dioxide, six molecules of water, and up to 30 molecules of ATP, which is directly used to generate energy, from each molecule of glucose in the existence of enough oxygen.
Thus, the by-product of both the procedures is ATP.
ATP is produced as a by-product of both glycolysis and aerobic respiration.
Further Explanation:
The accurate meaning of glycolysis is "splitting sugars." It is the process of producing energy through the breakdown of glucose. In the glycolysis process, a six-carbon sugar mainly called glucose is breakdown into two molecules of the pyruvate which are three-carbon sugars. This multiple step process produces ATP, NADH, and pyruvate. So, glycolysis is the process of the formation of pyruvate molecules from glucose with the help of many enzymes.
Glycolysis refers to the dissociation of sugar, generally the glucose into more convenient components to generate energy. The net end components of glycolysis are two NADH, two pyruvate, and two molecules of ATP.

Which two types of particles are present in equal numbers in an atom, but not in an ion? A. protons and electrons B. protons and neutrons C. inner-shell electrons and outer-shell electrons D. protons and inner-shell electrons
An atom consists of a central nucleus with contains positively charged particles called protons and uncharged particles called neutrons. Negatively charged particles called electrons revolve around the central nucleus along specific orbitals. In a neutral atom, the number of positive protons and negative electrons is same. A metal atom has the tendency to lose electrons from its outermost electronic shell (orbital) to form a positive ion (cation). As a result, the number of electrons decreases. On the other hand, a non-metal atom has the tendency to gain electrons to form a negative ion (anion). As a result, the number of electrons increases. Therefore, electrons and protons are the two types of particles that are present in equal numbers in an atom but not in an ion.
(Answer) (A) protons and electrons
The correct answer is option A which is protons and electrons.

when plants or animals perform aerobic cellular respiration
when plants perform photosynthesis
you can pick more than one
Final answer:
Oxygen is consumed when aerobic bacteria decompose dead algae, when forests are burned for land clearing, and during aerobic cellular respiration in plants or animals. Photosynthesis, however, produces oxygen and does not consume it.
Explanation:
Oxygen is consumed during several processes which involve aerobic metabolism. The following scenarios outline when oxygen would be utilized:
When aerobic bacteria break down dead algae in a pond, they use oxygen in a process known as aerobic respiration. During this process, the bacteria obtain energy by breaking down organic matter, releasing carbon dioxide and water as by-products.Oxygen is also consumed when forests are burned to clear land for farming. In this case, oxygen reacts with the carbon in wood during combustion, which results in the release of carbon dioxide, water, and energy in the form of heat and light.Plants or animals performing aerobic cellular respiration also use oxygen. This process involves using oxygen to break down glucose molecules to produce ATP, a source of energy, along with carbon dioxide and water as by-products.In contrast, during photosynthesis, plants actually produce oxygen rather than consume it.
