Is it possible for energy to be transferred directly from the first trophic level to the third trophic level? Explain.​

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Discuss mechanisms of disease transmission and processes of infectionss
nata0808 [166]
Diseases have multiple ways of infiltrating your body. Diseases can be transported through blood, air, and physical touch. Once the disease has infiltrated the body, it can spread through out the body in many ways. One of which is by feeding off of other cells energy and reproducing. The pathogens travel through the blood and irritate cells. The irritation of cells can cause the body to consume more energy, to repair the damage. This causes symptoms like tiredness, regurgitation, and sometimes in extreme cases, death.

Hey can someone please help with this ap bio question.
ozzi

Answer:

a) Individual 1

b) Overall, the higher the number of mutant alleles, the greater is the concentration of cysteine in urine relative to normal values.

c) The hypothesis may be correct. If number of mutant allele in SLC7A9 is higher than number of mutant allele in SLC3A1, then concentration of cysteine  in urine is lower. This means that transportation of cysteine is affected by a greater extent if mutant allele in present in SLC7A9 genetic sequence

d) concentration of cysteine is affected by mutant allele which is a complex protien. If complex protien is low cysteine is not transported back and its concentration in urine is higher

Explanation:

a) Can be inferred easily from table. Higher the mutant allel that is negative, higher is the concentration of cysteine. Hence greater the chances of cystinuria.

b) As explained in part a

c) Observe the pattern on concentration of cycteine and number of - allele. If cysteine is not transported back then its concentration in urine will be higher.

d) The complex protien helps in transportatino of cysteine by binding to it. In the absence of the ocmplex protien, cysteine tends to behave like polar molecule and stay in water that is in excess in urine.

The prostate, seminal glands, and bulbo-urethral glands produce __________, the liquid medium in which sperm leaves the body.
ycow [4]

The prostate, seminal glands, and bulbo-urethral glands produce Seminal fluid, the liquid medium in which sperm leaves the body.

<h3>What is Seminal fluid?</h3>
  • The seminal vesicles and prostate gland make a whitish fluid called seminal fluid, which combines with sperm to form semen when a male is sexually stimulated.
  • Fluid from seminal cysts is thick. It contains fructose, citric acid, proteins, potassium, inorganic phosphorus, and prostaglandins. When the fluid incorporates with sperm in the ejaculatory duct, the fructose evolves the direct source of energy for the sperm outside a man's body.
  • semen, also named seminal fluid, is fluid that is ejected from the male reproductive tract and includes sperm cells, which are competent for fertilizing the female's eggs. Semen also prevents liquids that connect to form seminal plasma, which helps keep the sperm cells possible.

To learn more about Seminal fluid, refer to:
