A land-dwelling organism, A, and an aquatic single-celled organism, B, are represented below.

Sergio039 [100]

Using the image that represents the land-dwelling organism and an aquatic single celled organism. The statement that best explains how A and B are able to survive in their environments is…

Answer: A) The organelles in B perform similar functions to the organ systems in A.

Please see image attached to better understand how we arrived to the conclusion.

I hope it helps, Regards.

You are a dog breeder and are interested in two traits that you believe are inherited by simple genetic loci glossy (G) coat is

Paul [167]

Answer:

GL, Gl, gL, and gl

Explanation:

The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:

GGLL, GgLL, GGLl, or GgLl

The dad is dull and short haired, the genotype would be ggll.

GGLL x ggll

Progeny = all GgLl (all glossy long haired)

GgLL x ggll

Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)

GGLl x ggll

Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)

GgLl x ggll

Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)

Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.

The parental gametes produced by the mom would be; GL, Gl, gL, and gl

Describe your diagnosis for the patient. How did the chlorine gas affect concentration difference, diffusion distance, and surfa

garri49 [273]

Answer:

The concentration difference is the difference of concentration in the blood when entering the lungs, increasing the difference increases the rate of diffusion. Diffusion difference is the distance between the respiratory membrane, increasing the distance causes a decrease in diffusion rate. The surface area of the lungs affects the available space for diffusion, decreasing the surface area decreases the diffusion rate

In the male reproductive system, the pituitary hormone _____ stimulates Leydig cells to secrete testosterone, and the pituitary

Katena32 [7]

Answer:

Luteinizing hormone (LH) stimulates Leydig cells to secrete testosterone

Follicle stimulating hormone (FSH) stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis

Explanation:

Under the influence of gonadotropin-releasing hormone, the anterior pituitary releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In males, LH stimulates interstitial cells of testes (Leydig cell) to secrete the hormone testosterone. FSH acts indirectly to stimulate spermatogenesis by causing the release of androgen-binding protein (ABP) from the Sertoli cells. The function of ABP is to maintain the higher concentrations of testosterone to stimulate the final steps of spermatogenesis in the seminiferous tubules.

Which of the following is primarily responsible for limiting the number of trophic levels in most ecosystems?

solniwko [45]

Answer:

(B) Energy transfer between trophic levels is almost always less than 20% efficient.

Explanation:

The ultimate source of energy on the Earth is the Sun. The energy coming from the Sun is captured by green plants by the photosynthesis. During photosynthesis sun energy is fixed into chemical energy (carbohydrate). So, in an ecosystem energy flow is unidirectional (from sun to the green plants). The fixed chemical energy from green plants is transferred to the herbivores then to carnivores through food. When one organism eats another organisms, only 10 % of the energy present in the organism is transferred as a food for the next organism and a large amount of energy is lost as heat into the environment. Thus, energy keeps on decreasing when stored energy moves from producers to top consumers. Thus, less than 20% energy transfer limits the trophic levels in most of the ecosystem.
