A plant in a dark room is being set up with a light source so it can photosynthesize. Pick from the following list the best choice for this light source to maximize photosynthesis.

Answers

Answer 1

Answer:

A bright light close to the plant.

Explanation

Plants grown in bright light had higher rates of apparent photosynthesis per unit leaf area in bright light, and slightly lower rates in dim light than did those of plants grown in dim light. Dark respiration rates were higher in plants grown in bright light than in plants grown in dim light and the decline of photosynthesis with increasing leaf age was faster.

The rate of apparent photosynthesis in bright light of the first leaf to become fully expanded after plants were transferred from bright to dim light was lower than that of plants remaining in bright light. The decline in the rate of photosynthesis of a leaf already fully expanded at the time of transfer was not affected. Transferring from dim to bright light increased the rate of photosynthesis of the next expanded leaf; it also increased the rate of an already fully expanded leaf during the first week in bright light.

What is phycology is study of:

A symbiotic relationship in which one species benefits and the other is harmed but not immediately killed is known asmutualism.
predation.
commensalism.
parasitism.

Answers

This type of a relationship where only one species benefits and the other is harmed is known as parasitism. The other species is not killed immediately, at least not as long as the first species, or the parasite, needs them. As long as the victim provides enough sustenance for the parasite to live, they will be necessary and not killed off. The moment the victim has nothing else to offer to the parasite, it is probably going to die.

A symbiotic relationship in which one species benefits and the other is harmed but not immediately killed is known as parasitism.

What is parasitism?

Parasitism is a type of ecological relationship where one species is harmed and the other is benefited by this interaction.

Predation is another type of ecological relationship where one species known as the predator, kills and eats another organism called prey.

Commensalism is a type of ecological relationship where one organism benefits and the other organism neither benefits nor harm.

In conclusion, a symbiotic relationship in which one species benefits and the other is harmed but not immediately killed is known as parasitism.

Which trace fossils are created when a worm travels through the soil and the impression is filled with hardened sediment?

Answers

The answer is Repichnia.

Fossils which consists of impression made on the subtrate by an organism is called trace fossils. It is also know as ichnofossils. Examples of trace fossils are footprints. There are different classification of trace fossil such as repichnia. Repichnia are the surface traces of creeping and crawling just like the path created by the worms.

Hemophilia is an X-linked recessive disorder (Xh) that is passed through generations and can be traced by using a pedigree. How high or low is the probabilty that a female child of Charles and Marie would suffer from hemophilia? A. 0 percent B. 25 percent C. 50 percent D. 100 percent

Answers

Without a pedigree chart, it is not possible to answer this question. However, given this is a HS bio class question, they are probably looking for the simplistic answer "A", zero percent, based on the erroneous notion that women cannot have hemophilia. Women carriers of a defective gene coding for hemophilia frequently do themselves have mild or moderate hemophilia and, in very rare cases, severe hemophilia.

If you have a transfer RNA molecule with the anticodon CCC what is the amino acid being carried in during elongation?

Answers

Answer:

please give me brainlist and follow

Explanation:

At one end, the tRNA has an anticodon of 3'-UAC-5', and it binds to a codon in an mRNA that has a sequence of 5'-AUG-3' through complementary base pairing. The other end of the tRNA carries the amino acid methionine (Met), which is the the amino acid specified by the mRNA codon AUG.

A student was visiting a friend at her home. Her friend owned two cats. After playing with the cats fora while, the student began to sneeze. Her nose began to run and her eyes became red, watery, and
itchy. It also became hard for her to breathe. A few minutes after leaving her friend’s home, the
symptoms disappeared.
Provide a biological explanation for the symptoms the girl developed at her friend’s house. In your
response, be sure to:
• state one reason why her symptoms are not likely due to an infectious agent

Answers

Answer: This girl is allergic to cat´s hair.

Explanation:

The substance that provokes allergy to cats is a protein produced in the sebaceous glands and that can be found in the cats´ hair. It can be found in clothes, walls, beds, among other places. As it can also be suspended in air, a person can easily breathe it. In a house with cats, these proteins are present in important amounts.

An allergic reaction is an abnormal response of the immunity system to a substance considered strange to the body, in this case, the protein or the cat´s hair. These strange substances are called allergens.

The allergen gets in contact with the body for the first time in a sensibilization face. The immunity system considers that this is a strange dangerous substance for the body. In this first stage, the subject submitted to the presence of the allergen does not show any symptoms. But in a second contact, the organism reacts with allergic reactions.

There might appear symptoms in ayes and nose as irritations, stinging, cough, skin´s eruptions and difficulty to breath.
