C

Explanation:

Answer 2

Answer:

C. It is cold and dense so it rises

Explanation:

"Molten rock, i.e., magma, is less dense and more buoyant than the surrounding rock, as a result magma rises through Earth's crust. Most magma is trapped in the crust, but some erupts onto the Earth's surface as lava."

A human somatic cell is in g1 of the cell cycle. How many physical copies of the ldlr gene does this cell have?

Answers

A human somatic cell is in g1 of the cell cycle. The cell will have two copies of the ldlr gene.

Humans are diploid, which means that each chromosome has two copies.Since a diploid organism is produced by the union of two gametes, each of which contains one set of chromosomes (N), diploid cells (all the cells in our body aside from our gametes) have 2N. It helps to think of chromosomes as bundles of genetic data when discussing chromosome number (ploidy). Because each sister chromatid has genetic material (alleles) inherited from just one parent, they make up one chromosome.A diploid organism has two copies of each gene during G1 of interphase.

How does sodium regulate the uptake of glucose into enterocytes?

Answers

Answer:

Sodium regulates the absorption of glucose by the enterocytes.

There are two basic types of transport systems for glucose:

- Sodium dependent glucose transporters (SGLTs)

- Glucose transporters (GLUTs)

Sodium is transported into cells actively by SGLTs, and glucose is transported into cells passively. The co-transport system's energy source are the sodium ions. In addition to other tissues, the GI brush-border membrane contains a very high number of SGLTs.

There are as many as 6 more related proteins, mostly expressed in the kidney, and at least 3 SGLTs (SGLT1-3) have been described from different species. The extracellular side of the SGLTs has both N and C terminal ends, totaling up to 15 transmembrane domains.

The GLUTs enable the diffusion of glucose, and some of them can also move other hexose carbohydrates. Due to amino acid sequences in the four hydrophilic domains of the 12 transmembrane domains, certain GLUT proteins are tissue-specific.

If an organism with the genotype aabb produces gametes, what proportion of the gametes would be bb?

Answers

Assuming independent genes and normal meiotic events, the gametes of an individual with genotype aabb are ab, ab, ab, ab. There are no bb gametes. The answer is NONE.

What is a gamete?

A gamete is a haploid cell that results from the meiotic division of germ cells during gametogenesis.

These haploid cells have half the number of chromosomes of somatic and germ cells, and their destiny is to merge with another gamete to produce a new diploid cell.

During gamete formation, homologous chromosomes separate after crossing over, and finally, sister chromatids separate too, resulting in four haploid cells, each of them with a different allele combination.  

When genes are in different chromosomes or far from each other in the same chromosome, they express independent assortment during meiosis. These genes are independent.

Independent assortment means that during a meiotic event, alleles from two or more different genes distribute in gametes independently from each other.

Each gamete receives an allele of a gene that does not depend on nor influence the allele of another gene in the same gamete.

In the exposed example, the homozygous recessive genotype is composed of two diallelic genes ⇒ aabb

Genotype: aabbAllele combination ⇒ Gametes ⇒ ab, ab, ab, ab

Assuming independent genes, unless there is some sort of problem during meiosis, there are no gametes bb, because gametes result from the combination of both genes.

The answer is NONE. There are no gametes bb.

Compare the function of phototropism to the function of gravitropism. How does each of
these tropisms work?

(Hint: starch molecules and auxins should be part of your response.)

Answers

The function of phototropism can be compared best with the function of gravitropism by taking an example of statoliths (Starch molecules) in roots and auxin in stem.

Roots often bend away from light (i.e., exhibit negative phototropism) in the direction of gravity(i.e. exhibit positive gravitropism).

Whereas stem-like organs drive their growth toward the light (i.e., positive phototropism) and away from gravity (i.e., negative gravitropism) (i.e. positive gravitropism).

As in the instance of phototropism, positive tropisms react by migrating towards the direction of the stimulus source.

Auxin formation and blue light stimulation control this response's mechanism.

On the shaded side of the plant, where those cells are starting to elongate, the activation of the blue light results in a concentration of auxin, a plant hormone.

On the other hand, negative tropisms, like gravitropism in plant shoots, react by migrating away from the stimulus's source.

A unique type of cell called a statocyst contains statoliths, which are starch molecules that can settle within the statocysts in reaction to gravity.

These starch molecules accumulate on the bottom of the statocyst as they descend toward gravity, increasing auxin levels and encouraging cell elongation.

Hence, these two processes can be compared best with an example of statoliths (Starch molecules) in roots and auxin in stem.

However, the sustained use of a range of agro‐chemicals, in recent years, has resulted in an increase in the number of herbicide‐resistant weed species (Powles and Shaner, 2001), a shift in the weed flora of arable fields from one of mixed weeds to one dominated by grass weeds (Barr et al., 1993) and increasing environmental and public health concerns over the use of pesticides (Conway and Pretty, 1991).

There are 4 stages of mitosis - prophase, metaphase, anaphase, and telophase. Thereafter, the cytoplasm divides in a process known as cytokinesis.

At prophase, the nuclear membrane dissolves and the chromatin material condenses.

At metaphase, the chromosomes align at the center of the cell while the spindle fiber engages each of them from the opposite ends of the cell.

At anaphase, chromosomes are pulled apart and sister chromatids of the same chromosome begin migrating towards opposite ends of the cell.

At telophase, migration of chomatids complete.

Thereafter, the nuclear membrane reappears around each chromosome, the chromosomes decondense, and the cytoplasm divides to give two independent cells.

A food chain describes who eats whom in the wild. Every living thing – from unicellular algae to giant blue whales – needs food to survive. Every food chain is a possible pathway that energy and nutrients can travel through an ecosystem. The primary productivity of the grass is 200 units. There is a 10 fold decrease in the amount of energy units as we move upwards in production chain. So from grass to rabbits we lose energy. The foxes will only really have two units once it's decreased by 10 fold again. The grass does not get any energy from the decaying bodies of foxes, they get the minerals that they need to grow.  And so the correct answer to this question is 0 units because when the energy gets recycled from fox trophic level back to the grass trophic level it will be totally reduced.

At the end of the year, retiree benefits paid by the trustee were $6 million and cash invested in the pension fund was $7 million. What was the percentage rate of return on plan assets? When designing equipment for high-temperature and high-pressure service, the maximum allowable stress as a function of temperature of the material of construc- tion is of great importance. Consider a cylindrical vessel shell that is to be designed for pressure of 150 bar (design pressure). The diameter of the vessel is 3.2 m, it is 15 m long, and a corrosion allowance of 6.35 mm (1/4") is to be used. Construct a table that shows the thickness of the vessel walls in the temperature range of 300 to 500C (in 20C increments) if the materials of construction are (a) ASME SA515-grade carbon steel and (b) ASME SA-240-grade 316 stainless steel A group of students are members of two after-school clubs.
