Different genes are activated in the blood cell than in the liver cell.

Explanation:

All the cells in the body contain the same number of genes and genetic material DNA but not all genes are expressed in a single cell.

The highly regulated process of the genes in molecular biology promotes the expression of particular gene required.

Signals from the cell environment activate the transcription factor that binds to regulatory regions of the gene, hence transcribing and making proteins for the same.

The genes for both blood cell and the liver are different but will be present in all the somatic cells, the regulatory mechanism will choose the required gene to be transcribed.

Answer:

C) B, secretor

D) B, Nonsecretor

E) A, secretor

F) A, nonsecretor

Explanation:

When you cross AB(codominant) with O(homozygote recessive), it will result in 50% A(IaIo) and 50% B(IaIo).

The secretor gene is dominant and both parents are a heterozygote, so the ratio of offspring genotype should be 1 : 2: 1 while the ratio of the phenotype will be 3 secretors: 1 nonsecretor.  

The possible phenotype will be:

B nonsecretor

A secretor

A nonsecretor

B secretor

B nonsecretor

When individuals with Se/se (secretor) alleles and blood types AB and O mate, their offspring could exhibit the following phenotypes: A, Secretor (E); B, Secretor (C); and O, Secretor (G). This happens because the parents have at least one allele that allows them to be secretors, which will be passed on to the offspring.

The ABO blood group system is defined by the presence or absence of antigens A and/or B on the red blood cells. The presence of these specific antigens makes a person's blood type A, B, AB, or O. In this scenario, an individual with blood type AB has both the A and B antigens, while an individual with blood type O has neither antigen. The Se indicator denotes a 'secretor' or a person who can secrete their ABO antigens in their saliva and other body fluids.

Now, when an AB individual (Se/se) mates with an O individual (Se/se), their child can be born with blood type A, B, or O. As both parents are Se/se, meaning they have at least one allele for secretor status, all of their offspring will inherit at least one secretor allele, making them secretors, irrespective of their blood type. Therefore, the following phenotypes can indeed occur: A, Secretor (E); B, Secretor (C); and O, Secretor (G).

Answer: Humoral Stimulation

Explanation:

Humoral stimulus refers to the control of hormone release in response to changes in extracellular fluids. Humoral stimulus is also as result of reflex stimulation that releases hormone due to direct stimulation from changing levels of nutrients or ions in the blood, such as the ion concentration in the blood. Some hormones are secreted in direct response to changing blood levels of ions and nutrients.

Answer:

     When you grab a wild population of rats, you need to follow the scientific method as it is, and by doing that, you can discover if it is a variable expressivity or a continuous variation.

Explanation:

       First, you need to check the species, to see their patterns of length of tail, because that's mostly what you want to know. After stablishing this pattern, you'll check the variability of their variation on different generations. For example, you pick up a rat that is aged a month, and a rat that is aged 3 months, and then compare them to one another. After you've done this lots of times, you can check if this variable is just a random one, or if it is continuous throughout the generations.

Remaining part of the question

Based on these facts, does alonzo have a potential claim against the accounting firm?

Solution

As per the theory of Promissory estoppel a promise made by an employer or entity to an individual/entity or any other subject even without any formal consideration cannot breach the promise on any basis including the any incident causing sudden crisis in organization.  

The same happened with Alonzo and hence he can claim against his employer on the basis of Promissory estoppel theory.

The scenario is about law, specifically contract law and the concept of promissory estoppel. Alonzo took significant action based on a job offer that was later withdrawn, and thus may have a valid claim for compensation.

The situation Alonzo faces can be categorized under contract law. In this particular case, it seems that Alonzo might have a valid claim for promissory estoppel, a legal principle that stops a party from going back on a promise that led another party to act on that promise, suffering damages as a result.

Here, the California firm made a promise to Alonzo (employment), which he relied on to make significant life changes. The California firm did not follow through on their promise, resulting in damages for Alonzo (relocation expenses, lost opportunities). If Alonzo can prove these points in a court of law, he may be able to successfully claim compensation for his losses.

Explanation:

Regarding the situation explained in the question that "African Americans are not affected by the malaria disease because of a specific genetic trait that they possess and that trait provides them with protection" can be explained by the answer given in option B.

Being heterozygous, meaning possessing a dominant and a recessive allele regarding that genetic trait, in terms of sickle cell trait which is a gene that causes the individual's blood cells to be sickle shaped and balanced polymorphism which means carrying two different versions of a gene is an argument that is enough to prove that the above statement is incorrect because it means they have blood cells that can be affected by the malaria disease.

Answer:

Parental generation

F1 offsprings

Hybrid/heterozygous

Explanation:

A true breeding plant will always produce the same trait of a given gene when self-crossed. A truebreeding plant is also referred to as Homozygous because it contains identical alleles of a gene. Hence, they undergo meiosis or gamete formation to produce gametes containing the same allelic content.

When two truebreeding plants with two different traits for the same gene i.e. homozygous for different alleles of a gene, are crossed. They are referred to as the Parent or P generation. Their first offsprings called F1 (first filial) offsprings will possess a mixture or combination of the two parental alleles, hence, the F1 offsprings are called hybrids or are said to be heterozygous.

In Mendel's pea experiment, the true-breeding parent plants are called the P₁ generation, and the offspring are the F₁ generation, which are always heterozygous for the contrasting trait.

In a typical pea experiment like those conducted by Gregor Mendel, two true-breeding plants with distinct traits of a single character are called the P₁ or the parental generation. These plants were homozygous, meaning they had two identical alleles for the trait he was studying. The offspring produced from the cross of these P₁ plants are referred to as the F₁, or the first filial generation. These F₁ plants, as a result of the P₁ cross, will always be heterozygous for the contrasting trait, which means that genetically, they carry different alleles for the gene under consideration.

True, a DNA strand is replicated to yield a new strand with the same base sequence. This ensures genetic consistency across cell generations. The base sequence ACTTCGCATG would remain the same in the replicated strand.

The statement is true. When a DNA strand is replicated, the resulting strand has the same base sequence as the original strand. This happens through a process known as DNA replication. Let's take the DNA base sequence ACTTCGCATG as an example. During DNA replication, each base in the sequence pairs up with a complementary nucleotide: A with T, and C with G. Therefore, for the given DNA sequence, the replicated strand would also be ACTTCGCATG, albeit in a complementary manner. Thus, DNA replication ensures genetic consistency from one generation of cells to the next.

Explanation:

The primary source of the specificity of enzymes is their shape, which relates to the lock-and-key model

Hope this helps

plz mark brainliest

Have a nice day!!!!

The primary source of the specificity of enzymes is their shape, which complies with the lock-and-key model, meaning the enzyme's three-dimensional structure is specifically matched to bind with its substrate.

The correct option is 'C'.

Enzymes are highly specific biomolecules that accelerate chemical reactions.

This specificity comes from the unique three-dimensional shape of the enzyme's active site, which is complementary to the structure of its specific substrate.

According to the lock-and-key model, the molecular shapes of the active site and the substrate are perfect matches, akin to a key fitting into a lock. This model emphasizes that the enzyme's structure is tailor-made to bind to its specific substrate, facilitating the chemical reaction.

Furthermore, the induced fit hypothesis suggests that while enzymes have a precise shape, they can also adjust slightly to ensure the perfect fit with the substrate, enhancing the enzyme's catalytic efficiency.

The correct answer to the question 'Chondroblasts ________.' is: b. within the cartilage divide and secrete new matrix.

Chondroblasts, which are young cartilage cells, play an active role in the cartilage development by dividing and secreting new extracellular matrix. The extracellular matrix, made up of collagen and elastin fibers, provides support and elasticity to the cartilage. This continues until the cells become mature chondrocytes, which are then located in the spaces called lacunae. Chondroblasts are part of the endochondral ossification process, where they form a hyaline cartilage diaphysis template in long bones.

Upon a set of complex developmental signals, this matrix begins to calcify. When the matrix calcifies, this prevents the diffusion of nutrients thus causing some chondrocytes to die and creating cavities within the diaphysis cartilage. Eventually, these cavities become filled with blood vessels and osteoblasts, which modify the calcified cartilage matrix into spongy bone.

The most likely direction of the prevailing winds across the Big Island of Hawaii is northeast.

Explanation:

The island of Hawaii, like all the other major Hawaiian Islands, is affected by the trade winds. These trade winds bring cool air to the islands from the north, often resulting in precipitation along inland/mountain and windward areas.

All of the Hawaiian Islands have both a windward and a leeward side. In general terms, the windward side is the wet, rainy, and therefore more lush, green, and tropical section. The windward side faces North or East, where it receives the benefit of the cool, trade-wind breeze.

Answer:

"the genes on DNA get transcribed into RNA, which get translated into a protein"

Explanation:

The central dogma is an important principle to biology, explaining the flow of information from DNA to functions that the cell can carry out. The central dogma says DNA --> RNA --> protein. Proteins carry out most biological functions in cells and organisms.

Genes on DNA have to be copied into a message in the form of RNA. DNA and RNA use the same language, so the message is transcribed (i.e. copied). The RNA then takes this message to the protein synthesis machinery, which uses a different language. Therefore, the RNA has to be translated into protein sequences
