CRISPR is a bacterial immune system.

The immune system protects your toddler's frame from outside invaders. those consist of germs including bacteria, viruses, fungi, and pollutants (chemicals made by means of microbes). The immune machine is made up of various organs, cells, and proteins that work together.

People have three styles of immunity — innate, adaptive, and passive: Innate immunity: everybody is born with innate (or herbal) immunity, a type of preferred protection. For instance, the pores and skin act as a barrier to block germs from coming into the frame.

Infections like the flu virus, mono (mononucleosis), and measles can weaken the immune device for a quick time. Your immune system also can be weakened through smoking, alcohol, and negative nutrients.

Thyrotropin-releasing hormone is released by the hypothalamus, thyroid stimulating hormone is released by the pituitary, and thyroid hormones T3 and T4 are released by the thyroid gland. Individuals with Kallman Syndrome will have a disruption in this endocrine axis.

Kallmann Syndrome is characterized by delayed or absent puberty as well as a poor sense of smell. This condition is a type of  hypogonadotropic hypogonadism, which is caused by a lack of product of certain hormones that regulate sexual development. These hormones are typically produced in the hypothalamus, a region of the brain. Males with hypogonadotropic hypogonadism constantly have a undescended testes( cryptorchidism). Most affected individualities don't develop secondary coitus characteristics during puberty, similar as facial hair growth and voice heightening in males, the launch of yearly ages( period) and bone development in ladies, and a growth spurt in both relations.

D) Predation is beneficial for ecosystems because it regulates population growth and promotes natural selection.

Through predation, predators help maintain the balance of prey populations, preventing overcrowding and overconsumption of resources. This balance allows various species to coexist within an ecosystem, promoting biodiversity.

Furthermore, predation contributes to natural selection by targeting weaker or less fit individuals within a population. This selective pressure encourages the development of beneficial traits and adaptations that increase the survival and reproductive success of prey species.

Over time, this process leads to the evolution of species better adapted to their environment, fostering overall ecosystem resilience.

In conclusion, predation plays a crucial role in maintaining healthy ecosystems by regulating population growth and driving natural selection. This beneficial interaction helps preserve biodiversity and promote the continued evolution of species within their environment.

The evolutionary advantages of DNA having thymine instead of uracil include:

Thymine base pairs using hydrogen bonds: Thymine forms stable hydrogen bonds specifically with adenine, ensuring accurate base pairing during DNA replication and transcription, which helps maintain the integrity and fidelity of genetic information.

Cytosine can be readily converted into uracil: This conversion allows for efficient DNA repair mechanisms to detect and correct potential errors in DNA, enhancing the accuracy of genetic replication and minimizing mutations.

Uracil is recognized by DNA repair systems: By having thymine instead of uracil, DNA repair systems can distinguish between normal bases and potentially harmful uracil, enabling the identification and removal of uracil residues to maintain genomic stability.

Thymine is more limited in its base-pairing than uracil: The restricted base-pairing ability of thymine reduces the likelihood of mispairing during DNA replication and transcription, contributing to the accuracy and fidelity of genetic information transfer.

The electron transport chain in cellular respiration produces a total of 10 ATP molecules.

The electron transport chain is the final step of cellular respiration that occurs in the inner mitochondrial membrane in eukaryotic cells. It involves a series of electron carriers that pass electrons down the chain, creating a proton gradient across the membrane.

This proton gradient drives the synthesis of ATP through chemiosmosis, a process in which the ATP synthase enzyme uses the flow of protons to generate ATP.

However, the question specifically asks for the ATP produced by the electron transport chain alone, not counting chemiosmosis. During the electron transport chain, three proton pumps (complexes I, III, and IV) actively pump protons across the membrane, creating a proton gradient.

This gradient is used to transport electrons and ultimately generate ATP in chemiosmosis. Each proton pump contributes to the production of about 3 ATP molecules. Therefore, without considering chemiosmosis, the electron transport chain itself produces a total of 3 ATP molecules per proton pump, which is a total of 3 × 3 = 9 ATP molecules.

Additionally, a direct ATP synthesis occurs during the electron transport chain, producing 1 ATP molecule by complex V (ATP synthase). So, the electron transport chain alone produces a total of 10 ATP molecules in cellular respiration.

A naive helper T cell can develop into either a TH1 or TH2 effector helper cell when an antigen-presenting cell activates it in a peripheral lymphoid tissue. The cytokines that these two types of functionally separate effector helper T cells release allow for easy differentiation.

The two types of T cells perform indistinctly due to their various cytokine patterns. B-cell antibody production, especially IgE responses, is generally well supported by TH2 cells. The opposite is true; TH1 cells cause delayed-type hypersensitivity reactions.

A helper T cell can assist in the activation of other cells once it has been transformed into an effector cell by an antigen-presenting cell. It accomplishes this by both exhibiting costimulatory proteins on its surface and secreting a range of cytokines.

The product of the concentration of the enzyme and its substrate and the catalytic rate constant is known as the instantaneous velocity, or catalytic rate. The initial velocity of a reaction is the amount of product produced in a given amount of time at the start of the reaction. This characteristic is necessary for all enzyme-catalyzed reactions.

Answer:

66986.51 g/mol

Explanation:

According to this question, Hemoglobin- an oxygen carrying compound in the blood, is found to contain 0.3335% iron (Fe) by mass.

* One molecule of hemoglobin contains four atoms of iron

If 1 atom of Fe = 55.85g/mol

Then 4 atoms = 4 × 55.85 = 223.4g/mol

So there are 223.4g/mol of Fe in one molecule of hemoglobin

If hemoglobin contains 0.3335% iron by mass, this mathematically means that:

223.4g/mol of Fe ÷ molar mass of hemoglobin = 0.3335%

That is;

223.4/M.M = 0.3335/100

Cross multiply

0.3335 M.M = 22340

M.M = 22340 ÷ 0.3335

M.M = 66986.51

Hence, the molar mass of hemoglobin is 66986.51g/mol.
