The various processes of cellular respiration take place in the cytoplasm and mitochondria. By moving between these different chemical environments our cells are able to generate ATP more efficiently. What compartments do Gylcoysis, the Krebs Cycle and the Electron Transport Chain occur in?

Answers

Answer 1

Answer:

Glycolysis: Cytoplasm

Kreb's cycle: Mitochondrial matrix

Electron transport chain: Inner mitochondrial membrane

Explanation:

Glycolysis is the first stage of cellular respiration and occurs in the cytoplasm. It does not require the presence of oxygen. Glycolysis enzymes are present in the cytoplasm. Pyruvate formed by the glycolytic breakdown of glucose enters the mitochondrial matrix and undergoes oxidative decarboxylation to form acetyl CoA. Acetyl CoA enters the Kreb's cycle. All the reactions of Kreb's cycle occur in the matrix of mitochondria.

The reducing powers NADH and FADH2 enter the electron transport chain to become oxidized again. The electron transport chain consists of a series of electron carriers embedded in the inner mitochondrial membrane.

a. Wolff's law
b. Synergistic dominance
c. Autogenic inhibition
d. Davis's law

Answers

Answer:

b. Synergistic dominance

Explanation:

The stabilizing muscles will always be synergistic, since only from the synergies (hence the term synergist) that arise from joint work is efficient and controlled movement possible. However, not all synergists will be stabilizers. Stabilizer will be one that, thanks to the geometric arrangement of its fibers, will have the ability to maintain alignment in the joint and stable the axis of rotation.

In the case of knee extension, we would have as stabilizers all the antagonists who, because the flexion axis is virtual and not physical, must maintain the stability of said axis. If the axle were physical, such as the wheel in a horse carriage, or on a skateboard through the bearings, the antagonistic muscles would not be necessary for this purpose, because the fixed axis would maintain the position. Since the joints of living beings do not have a fixed physical axis, it is the muscles themselves, specifically the antagonists, who must be responsible for maintaining the stability of the joint creating a virtual axis on which rotation occurs.

A leukocyte is responsible for: bringing oxygen to the other body cells fighting disease by phagocytosis or antibody production causing muscle contraction conducting nervous impulses throughout the body

Answers

Final answer:

A leukocyte, or white blood cell, is vital in the immune system, responsible for defending the body against disease through phagocytosis or antibody production.

Explanation:

A leukocyte, commonly known as a white blood cell (or WBC), is an integral component of the immune system responsible for protecting the body against illness. Leukocytes engage in various defense mechanisms, including phagocytosis and antibody production.

Neutrophils and macrophages are types of leukocytes that actively engulf and digest pathogens, a process known as phagocytosis. Other leukocytes, such as lymphocytes, primarily function in the immune response by making antibodies tailored to foreign antigens.

Additionally, leukocytes are involved in inflammation, an immune response that helps to isolate and heal the affected area.

Population 2 has 150 beetles and 15 of them have brown spots, while 135 have red spots. Population 3 has 50 beetles, and five of them have brown spots. In which population is the frequency of the allele for brown spots the highest?

Answers

Answer:

Let's add the options to complete the question

a. Population 1

b. Population 2

c. Population 3

d. The frequency for allele for Brown spot is the same in all three populations

e. It is not possible to answer this question from the given data

The RIGHT ANSWER IS e

e. It is not possible to answer this question from the given data

Explanation:

It is not possible to answer this question from the given data because some variables or information are missing

In comparing three populations of ladybug beetles, the frequency of the allele for the recessive brown spots trait (calculated as the square root of the phenotype frequency) is the same across all populations (0.3162). Therefore, the frequency of the brown spot allele is equally high in all three populations.

We need to apply the principles of population genetics and use the Hardy-Weinberg formula. Population 1 has 20 beetles with a frequency of brown-spotted beetles of 2/20. Population 2 has 150 beetles with a brown spot frequency of 15/150. Population 3 has 50 beetles with a brown spot frequency of 5/50.

In each case, the frequency of the recessive allele (r) representing brown spots can be calculated as the square root of the frequency of the recessive phenotype, since all brown beetles are homozygous recessive (rr).

Population 1:

Frequency of rr = 2/20 or 0.1.

Frequency of r allele = √0.1 = 0.3162.

Population 2:

Frequency of rr = 15/150 or 0.1.

Frequency of r allele = √0.1 = 0.3162.

Population 3:

Frequency of rr = 5/50 or 0.1.

Frequency of r allele = √0.1 = 0.3162.

Interestingly, in all three populations, the frequency of the allele for brown spots is the same (0.3162). So, the answer is that all three populations have the same highest frequency of the recessive allele for brown spots.

Answers

Answer:Spurs on it's hindlimbs

Explanation:the duck-billed platypus is has Spurs on it's hindlimbs that's secretes venom.this venom is for mating purpose and it's present only in males

The male duck-billed platypus has sharp spurs on its hind legs that deliver venom, causing severe pain and swelling. This is mainly used during territorial disputes in the mating season.

The duck-billed platypus delivers its venom through a pair of sharp spurs on the hind legs near the ankle, which are connected to a venom-producing gland in the thigh. This venom consists of a mixture of neuroactive peptides, which are short proteins. The male platypus uses his venomous barbs predominantly during mating season when competing for territory. While not typically lethal, a platypus's venom can cause severe pain and swelling that persists for an extended period.

Which of the following is the term for an abnormally low white blood cell count?

Answers

Answer:

The correct answer is- Leukopenia

Explanation:

White blood cells are present in our blood which protect our body from foreign antigens like bacteria, viruses, etc. When these white blood cells decrease abnormally in number then this condition is called leukopenia.

White blood cells contain different cell which protect our body from different type of infections. So there are different types of leukopenia according to the particular white blood cell whose number became low.

For example when neutrophils number in the body decrease it is called neutropenia. So the correct answer is leukopenia.

Final answer:

Leukopenia is the term for an abnormally low white blood cell count which increases individual's risk for disease due to immune system weakness.

Explanation:

The term for an abnormally low white blood cell count is Leukopenia. This condition occurs when too few leukocytes (white blood cells) are in the blood. A low white blood cell count leaves the individual at a higher risk for disease since these cells play a significant role in the immune system. Their production begins in the bone marrow, and abnormalities with this can cause deficient counts. Matters are further complicated when abnormally low lymphocyte counts occur, as a result of chronic illness or immunosuppression.

Using the principle of independent assortment, complete the Punnett square to show the results of an F1 cross between two individuals heterozygous for both pod color (C = green and c = yellow) and pod shape (S = smooth and s + constricted). The gametes and some of the genotypes of the F2 offspring are given.

Answers

Answer:

9:3:3:1   ( 9 dominant pod color and shape, 3 heterozygous pod color and  homozygous recessive pod shape, 3 homozygous recessive pod color and heterozygous  pod shape and 1  recessive homozygous pod color and pod shape)

Explanation:

Mendel's law of independent assortment posits that the alleles of two (or more) different genes get assorted into gametes independently of one another. This implies that the allele  a gamete receives for one gene does not influence the allele received for another gene.

In the question  given;

We will take a critical look at the  cross between  two pure-breeding pod color and pod shape:

Pod color (green) = C

Pod color (yellow) = c

Pod Shape (smooth) = S

Pod shape (constricted) = s

The F1 progency of the cross between the heterozygous pod color and pod shape will be:

Cc  × Ss

= CS, Cs, cS, cs

From the question, we are to complete the punnett square of the results of the F1 generation, i.e if the F1 progeny assorts independently, what will be the results (F2 generation)

 i.e :  CS, Cs, cS, cs × CS, Cs, cS, cs

The Punnet Square is in the attached file below.

The results of this dihybrid cross are as follows:

CCSS, CCSs, CCSS, CcSs, CCSs, CcSs, CcSS, CcSs, CcSs  (all dominant pod color and shape) "9"

CCss, Ccss, Ccss  (heterozygous pod color and  homozygous recessive pod shape) "3"

ccSS, ccSs, ccSs (homozygous recessive pod color and heterozygous pod shape)

ccss (recessive homozygous pod color and pod shape)

We can therefore conclude that the results of the Punnet Square of the F1 generation is in the ratio of 9:3:3:1

The oxygen that is released as o2 during photosynthesis came from _____________ molecules.

Answers

Answer:

Water (H2O)

Explanation:

Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.

Final answer:

The oxygen (O2) released during photosynthesis comes from water molecules. This happens during the light-dependent reactions of photosynthesis where water molecules are split and oxygen is released as a by-product.

Explanation:

The oxygen that is released as O2 during photosynthesis comes from water molecules. The process of photosynthesis occurs in plants, algae, and some bacteria where light energy typically from the sun is used to convert carbon dioxide and water into glucose (a sugar) and oxygen. In detail, during the light-dependent reactions of photosynthesis, water molecules are split, thereby releasing oxygen as a by-product. This oxygen is what we, and other animals, breathe.

All your cells contain proto-oncogenes, which can change into cancer-causing genes. Why do cells possess such potential time bombs?

Answers

The given question is incomplete. The complete question is:

Question: All your cells contain proto-oncogenes, which can change into cancer-causing genes. Why do cells possess such potential time bombs?

A. Cells produce proto-oncogenes as a by-product of mitosis.

B. Proto-oncogenes are necessary for the normal control of cell growth and division.

C. Proto-oncogenes protect cells from infection by cancer-causing viruses.

D. Proto-oncogenes are unavoidable environmental carcinogens.

E. Proto-oncogenes are genetic junk that has not yet been eliminated by natural selection.

Answer:

B. Proto-oncogenes are necessary for the normal control of cell growth and division.

Explanation:

The process of cell division is under tight regulation by a family of extracellular growth factors, specific proteins that trigger cell division and the tumor suppressor genes that normally inhibit cell division. Defects in these genes can lead to cancer.  

For example, the protein encoded by tumor suppressor gene p53 stimulates the synthesis of p21 which in turn inhibits the cyclin-cdk2 to block entry of G1 cells into the S phase until the DNA is repaired. Mutations in tumor suppressor genes retinoblastoma and p53 allow cells to proceed to the S phase irrespective of DNA repair.

Likewise, a mutation in ras proto-oncogene encodes a protein with no GTPase activity. The mutant Ras protein is always in its activated form, regardless of the signals from normal receptors. This makes the cells to divide in an uncontrolled manner.  

Final answer:

Proto-oncogenes are genes essential for normal cell function, however, when mutated, they may cause uncontrolled cell division leading to cancer. Other factors, such as underactive tumor suppressor genes and epigenetic changes, can also contribute to cancer development. Active research is underway to utilize the reversibility of these changes for cancer treatment.

Explanation:

Every cell in our body contains proto-oncogenes, which are essential for normal cell function and growth. However, these can mutate into oncogenes, setting off the equivalent of biological 'bombs' by causing uncontrolled cell proliferation, leading to cancers such as Burkett's Lymphoma. Proto-oncogenes and tumor suppressor genes work in tandem, like the accelerator and brakes of a car, to control cell cycle. Unwanted cell division and proliferation can occur due to three main scenarios: proto-oncogenes becoming overactive, tumor suppressor genes becoming underactive, or through epigenetic alterations.

Epigenetic changes such as methylation and deacetylation can silence genes, and these changes are common in cancer. Because these changes are temporary and reversible, designing drugs and therapies that can reverse these changes is an area of active research in cancer treatment.

Other proteins that influence the cell cycle, in addition to cyclins and cell-surface receptors for growth factors, have potential oncogenetic properties. An example is the Cdk gene, which when altered, can speed up cell cycle progression.
