Answer:

Endangered

Explanation:

Endangered species are organisms that are at risk of extinction if deliberate efforts are not made to conserve them due to a rapid decrease in their population.

Hence, if a marine biologist writes an article about saving whales and labels them as endangered species, all efforts should be geared towards saving the animals lest they go extinct and leave a vacuum in the functioning of the ecosystem.  Every species have the critical roles they play in the functioning of the ecosystem and the extinction of any particular species represents a loss that might not be replaceable.

The fox population can be modeled using an exponential growth function of the form P(t) = ab^t, where P(t) represents the population at time t, a is the initial population, b is the growth factor, and t represents the number of years.

In this case, the population in the year 2000 was given as 23500. We can use this information to find the values of a and b in the exponential growth function. Since the population has an annual growth rate of 5 percent, the growth factor (b) would be 1 + growth rate = 1 + 0.05 = 1.05.

To find the value of a, we substitute the given population value for the year 2000 into the exponential growth function: P(0) = ab^0 = a(1.05)^0 = a. Therefore, a = 23500.

Now we have the values of a and b, and the exponential growth function for the fox population becomes P(t) = 23500 * (1.05)^t, where t represents the number of years since the year 2000.

This function can be used to estimate the fox population for any given year after 2000 by substituting the desired value of t into the equation.

Answer and explanation:

The model designed by the student is useful to explain in a simple way the question of the evolution of the homo gender (our gender), mainly in basic education, but it may seem inconsistent at higher educational levels.

Humans and chimpanzees, according to the theory of evolution, descend from a relatively recent (about 7 million years) common ancestor.

These same species, as well as lemurs, baboons and all other primate species, share an ancestor who lived longer.  Likewise, there is an even older ancestor that originated primates, bats, whales and all other groups of mammals .

The fact that chimpanzees have a DNA very similar to ours (about 98.5% similarity between code sequences) is because the successive evolutions from this common ancestor were not very drastic, besides the fact that they are in a branch more close to ours from the moment of separation of evolutionary lineages.

Annual rings in mature woody dicot stems are composed of light and dark sub-rings due to the different rates of growth during the spring and summer seasons.

The annual rings in woody dicot stems are formed by the activity of the vascular cambium, which is a layer of cells that divides and produces new cells towards the inside and outside of the stem. During the spring, when there is plenty of water and nutrients available, the cambium produces larger and thinner-walled cells, resulting in the light-colored sub-ring.

In the summer, when water and nutrient availability decreases, the cambium produces smaller and thicker-walled cells, resulting in the darker sub-ring. This variation in growth rates is due to changes in environmental conditions, and the resulting pattern of light and dark sub-rings can be used to determine the age and growth history of a tree or woody plant.

The given statement "About 10% of the carbon dioxide carried in the blood is simply dissolved in the plasma." is false because about 10% of carbon dioxide (CO₂) carried in the blood is not simply dissolved in the plasma. The majority of CO₂ in the blood is transported in different forms.

One of the main ways CO₂ is carried in the blood is through its conversion into bicarbonate ions. This process occurs in red blood cells and is facilitated by an enzyme called carbonic anhydrase. Carbon dioxide diffuses into red blood cells, where it combines with water to form carbonic acid, which then dissociates into bicarbonate ions and hydrogen ions.

The bicarbonate ions are then transported out of the red blood cells and into the plasma, while chloride ions move into the red blood cells to maintain electrical neutrality (chloride shift).

The bicarbonate ions are the primary form in which CO₂ is transported in the blood, accounting for approximately 70% of the total CO₂ transport. Another portion of CO₂ binds directly to hemoglobin in red blood cells, forming carbaminohemoglobin, which accounts for about 20-25% of CO₂ transport.

Only a small fraction of CO₂ (less than 10%) remains dissolved in the plasma as a result of its solubility in blood. This dissolved CO₂ plays a minor role in overall CO₂ transport.

In summary, the statement that about 10% of the carbon dioxide carried in the blood is simply dissolved in the plasma is false. The majority of CO₂ is transported in the form of bicarbonate ions, with a smaller portion binding to hemoglobin, while only a small fraction remains dissolved in the plasma.

The normal human pancreas contains about 1 million islets. The islets consist of four distinct cell types, of which three (alpha, beta, and delta cells) produce important hormones; the fourth component (C cells) has no known function.

The pancreas has both exocrine and endocrine functions. The pancreatic islet cell types include alpha cells, which produce glucagon; beta cells, which produce insulin; delta cells, which produce somatostatin; and PP cells, which produce pancreatic polypeptide. Insulin and glucagon are involved in the regulation of glucose metabolism. Insulin is produced by the beta cells in response to high blood glucose levels. Target cells are better able to absorb and utilize glucose, as well as store extra glucose for later use. Diabetes mellitus, a condition marked by elevated blood glucose levels, is brought on by a malfunction in the synthesis of insulin or target cell resistance to its effects. In reaction to low blood glucose levels, the pancreatic alpha cells create and secrete the hormone glucagon. Blood glucose levels are raised through mechanisms like the breakdown of glycogen into glucose, which is stimulated by glucagon.

Answer:

Histidine- Proline- Tryptophan- Stop codon

Explanation:

The mRNA strand in the question is produced as a result of a process called TRANSCRIPTION. However, the mRNA transcript is further used to synthesize an amino acid sequence in a process called TRANSLATION. The mRNA sequence is read in a group of three nucleotide bases called CODON.

Each codon specifies an amino acid which is represented in the GENETIC CODE. In this case, a sequence of mRNA strand is given as: CACCCAUGGUGA

The following codons in the sequence specify the following amino acid:

CAC - Histidine

CCA - Proline

UGG - Tryptophan

UGA - Stop codon

Hence, the amino acid sequence encoded by the given mRNA strand is Histidine- Proline- Tryptophan- Stop codon.

N.B: After a stop codon (UGA, UAA, UAG) is encountered, the translation process stops.

A female human has 46 chromosomes, which are arranged in 23 pairs. One chromosome of each pair is inherited from the mother and the other is inherited from the father.

In a female, one of the chromosomes in each pair is an X chromosome, while the other chromosome can be either an X chromosome or a Y chromosome. This results in a total of two X chromosomes in a female and one X and one Y chromosome in a male.

Therefore, if the lab worker counted 23 pairs of chromosomes and observed two X chromosomes, she could conclude that the chromosomes come from a female.

The aforementioned claim is accurate.  Intramembranous ossification takes place throughout lifetime.

The long bones, clavicles, flat bones, and the skull are created throughout fetal development by a process called intramural ossification, which also takes place when a bone is broken.

In essence, this process dictates how mesenchymal stem cells differentiate into osteoblasts, which later differentiate into osteocytes. Basically, what happens is that the mesenchymal cells start to multiply in response to a stimulation and form a structure called a nidus. Osteocytes, the fundamental building block of bones, are formed as a result of the replication, growth, and specialization of these cells. The mesenchymal cells will modify and adapt in a number of ways in order to lengthen, grow, and finally form the tissue.

Answer:

The first one, as there is little to no evidence as nothing existed to witness the big bang, nor are real remnants of it that are enough to prove it real.

Explanation:

Polygenic traits do not follow Mendelian inheritance patterns because multiple genes are involved.

Polygenic inheritance is a type of quantitative inheritance in which multiple independent genes have a similar or additive effect on a single quantitative trait. A polygene is a gene that, in conjunction with other genes, has a minor effect on phenotype. Because the effect of a single gene is so small, it is difficult to detect.

Multiple genes have the same effect. Each allele has an additive or cumulative effect. Polygenic inheritance differs from multiple alleles in that three or more alleles are present in the same locus, with any two alleles present in an organism, such as the ABO blood group system, which is controlled by three alleles. There is no epistasis, or masking of the expression of an allele from a different locus.
