Where do sperm go after leaving the epididymis?
A. Vas deferens
B. Urethra
O C. Ejaculatory duct
D. Seminiferous tubules

Answers

Sperm goes to the vas deferens after leaving the epididymis, which is option A. Details about sperm cells can be found below.

What is sperm cell?

Sperm is the reproductive cell or gamete of the male. The sperm is responsible for the fertilization of a female gamete to form zygote.

The sperm cell is produced via a process called spermatogenesis which occurs in the testes.

The epididymis is a narrow, tightly-coiled tube where sperm are stored during maturation. However, the sperm enters the vas deferens after leaving the epididymis.

6.) State the principle of dominance? I

Answers

Answer:

Please find the answer below

Explanation:

According to the convener, Gregor Mendel, the law of dominance states that one allele of a gene called DOMINANT ALLELE possess the ability to mask the phenotypic expression of another allele called RECESSIVE allele.

This law explains that in a heterozygous state of a gene, the dominant allele will always be expressed over the other. For example, in the trait of height, if T is tall and dominant, it will mask the allele of the other phenotype.

There is a great diversity of metabolism in microbes, with new types being discovered regularly. For example, the use of nanowires by the ANME and SRB was only discovered relatively recently (the study described in the introduction was published in 2015). Understanding microbial metabolism is essential to understanding how these organisms function within an ecosystem, including understanding symbiotic associations such as that between ANME and SRB. The terminology below describes metabolic types. Match each metabolic type with the best description.

2. Autotrophs
3. Chemolithotrophs
4. Mixotrophs

Answers

Answer:

a. mixotrophs

b. autotrophs

c. syntrophs

d. phototrophs

e. heterotrophs

f. chemolithotrophs

g. chemotrophs

Explanation:

Autotrophs are organisms that can synthesize their own food using carbon dioxide (CO2) and water (e.g., algae, cyanobacteria, plants, etc). Syntrophs are organisms that utilize products from other organisms (e.g., mites that consume human dead-skin). Phototrophs are organisms that synthesize their own food by using the energy provided by sunlight (e.g., green plants). Heterotrophs are organisms that cannot synthesize their own food, obtaining energy and nutrients by consuming other organisms (e.g., animals). Mixotrophs are flexible organisms that obtain their food by using a mix of different sources of energy and carbon. Protists that combine autotrophy and heterotrophy are considered mixotrophs. Chemotrophs are organisms that obtain energy by the oxidation of electron donors from the environment, by using both organic sources (chemoorganotrophs) and inorganic sources (chemolithotrophs). Examples of chemolithotrophs include sulfur/iron-oxidizing bacteria, while chemoorganotrophs include the most known bacteria and archaea.

Answers

Answer:

D

Explanation:

When performing low-intensity activities, the oxidative system uses fats as a substrate to produce ATP. Thus, option D is correct.

What is the significance of oxidative phosphorylation?

The majority of the ATP required for higher animals and plants to sustain life is produced by oxidative phosphorylation, which is also in charge of establishing and preserving metabolic equilibrium.

The last phase of aerobic cellular respiration is oxidative phosphorylation. The production of many ATP molecules is the primary goal of oxidative phosphorylation.

The energy system that largely supports prolonged, low-intensity exercise is sometimes referred to as the aerobic system. By boosting oxygen availability and enhancing our capacity to metabolize fat for energy, it supports this kind of exercise.

Therefore, oxidative phosphorylation take place in mitochondria.

Which type of reproductive isolation occurs when there are differences in the size or shape of reproductive parts and may prevent interbreeding

Answers

Temporal isolation, in biology, a type of reproductive isolation mechanism among sexual organisms in which the differences in the timing of critical reproductive events prevent members of closely related species, which could otherwise breed with one another, from mating and producing hybrid offspring.

A prezygotic barrier called temporal isolation promotes speciation, or the creation of new species. Isolation on account of geography, reproduction, or behavior are other prezygotic obstacles.

What reproductive isolation occurs in temporal isolation?

A reproductive isolation process known as temporal isolation prevents members of closely related species from mating and producing hybrid offspring.

Temporal isolation occurs when essential reproductive activities occur at different times in sexual organisms.

When two or more species reproduce at different times, this is known as temporal isolation. For instance, three different orchid species might be found in the same rain forest.

Therefore, Each species possesses one-day-only blooms that need to be pollinated on that day in order to produce seeds.

Scientists build models based on what they know from previous research to derive testable hypotheses.Independently, both Watson and Crick and their competitor Linus Pauling constructed an incorrect triple-helix model with the nitrogenous bases arranged so they were on the exterior of the molecule and the phosphate groups on the interior. What evidence caused Watson and Crick to revise their model (CHOOSE 2)

Answers

Answer:

Hello. You didn't show the answer options, but we can consider that Watson and Crick revised the DNA model after seeing DNA images taken through Franklin's x-ray and by observing the pairing of the nitrogenous bases.

Explanation:

For a long time it was believed that the DNA molecule had 3 strands, instead of two, however this information was inaccurate and although defended by some scholars it was somewhat controversial and showed the need for further investigation. With that in mind, Watson and Crick decided that it was necessary to evaluate DNA in a three-dimensional way and therefore, they obtained x-ray images of DNA molecules, taken by Franklin. In these images, it was possible to notice that the DNA had two strands, instead of three. To prove this discovery, Watson and Crick analyzed the nitrogenous bases discovered by Chargaff and the way they were paired, coming to the conclusion that the DNA had two strands.

California condors (Gymnogyps californianus) are listed on the IUCN Red List as being critically endangered. Since 2003, the California Condor Recovery Program has been reporting their demographic data. In 2012 they estimated the number of individuals living in the wild to be 235. If their intrinsic rate of natural increase is 0.089 ind/year, predict the size of the California condor population in 2022.

Answers

Answer:

 ≈ 572

Explanation:

Predict the size of the California condor in 2022

we can predict this value with this relation below

Nt  =  No*e^(rt)  --- ( 1 )

where ; Nt = Future population , No = initial population,  r = intrinsic rate of increase ,  t = time

No = 235

r = 0.089

t = 2022 - 2012 = 10

Insert values into equation  1

Nt = 235 * e^( 0.089 * 10 )

    = 235 * e^0.89

    ≈ 572

Therefore the size of the California condor population in 2022 ≈ 572
