Drug efficacy in cell lines is tested in research called drug dose-response studies. To determine which medications should be tested on patients first, they are frequently employed in cancer research.

1. Reaction

Regarding side effects or drug effectiveness, it refers to how a drug affects a pathologic or physiological process.

2. Dose

It is the dosage of a prescription or medication that a doctor advises patients to take and when.

3. Threshold

When a harmful chemical surpasses the body's defences above a certain threshold, they occasionally only produce a response.

4. ED50

The amount of a medication that will have an effect on 50% of the population receiving it is known as the median effective dose response.

5. LD50

50 % Lethal Dose. It gauges a substance's toxicity. It will calculate the amount of medication needed to eliminate half the population.

This suggests to you that Group of answer choices this primate shows a derived trait for an enhanced sense of smell as this trait is not commonly observed in mammal species this is a species of prosimian because it has an increased reliance on vision this is a species of anthropoid because it has an increased reliance on vision this primate must be a species of prosimian, as that suborder of primates still relies heavily on the sense of smell for many aspects of daily life

Answers

Answer:

this primate must be a species of prosimian, as that suborder of primates still relies heavily on the sense of smell for many aspects of daily life

Explanation:

The suborder prosimian belongs to primate mammals and is at a level inferior to the real monkeys.

Prosimians characterize as having an elongated head that culminates in the snout. They have big eyes with modifications in the retina that improve sight during the night. They are quadrupeds with a svelte body and soft hair. Their tail is long but not prehensile. They move from tree to tree by making use of their extremities. They have a dental comb to clean themselves and others.

Their snout is humid, and the sense of smell is much more developed than in other primates. They are the primates with the greatest sense of smell. Their olfactory bulb and glands are remarkably developed in concern with other primates. With their tree and nocturnal habits, they depend a lot in this sense to move, relate, be aware, and feed.

If two-hybrid Ff rabbits mate, what will the offspring look like?

Answers

Answer:

25% ff - homogeneous recessive

50% Ff - heterogenous

Explanation:

When two-hybrid Ff rabbits mate, then the offspring look like

25% FF - homogenous dominant25% ff - homogeneous recessive50% Ff - heterogenous.

What is Mating?

For the goal of sexual reproduction, opposite-sex or hermaphrodite organisms team together during mating. Two gametes join together during fertilisation. When two sexually reproducing creatures join their sex organs, internal fertilizations and insemination take place.

Punnett Square situations with two hybrid parents marrying are frequent. The heterozygous hybrid parents possess a single allele (A and a, Dominant and Recessive). There are four genotype outcomes that can happen if two hybrid parents mate.

Thus, when two-hybrid Ff rabbits mate, then the offspring look like

25% FF - homogenous dominant25% ff - homogeneous recessive50% Ff - heterogenous.

The brown-colored bones in each animal help to connect their limbs to a specific joint in the torso, or middle of their body. What type of structure do these bones represent, and what is their significance in terms of evolutionary relationships?

Answers

Answer: These structures connect their limbs to a specific joint in the torso or in the middle of their body. These structures can be identified as homologous, they are morphologically similar or possibly they derive from a common ancestral structure.

Explanation:

The brown color bones in animal help to connect limb homologous structures that connect their limb to the specific joint in the torso, this and having an evolutionary relationship.

What are bones?

If two bones split where they meet at a joint, it is termed a dislocation. The place where two bones connect and therefore can move is called a joint.

A displaced joint is one where the bones are out of alignment with each other having a significant role in evolution.

Despite their similar arrangements and being formed in a similar way throughout embryonic development, these structures have slightly different shapes and purposes, they refer to them as homologous structures.

Therefore homologous structures have an evolutionary relationship to connect brown-colored bones connect limbs to joint torso.

Most nonrenewable energy resources are burned for us to use their energy. Which of the following is a nonrenewable energy source that is NOT burned?
A) nuclear

B) coal

C) natural gas

D) biofuels

Answers

Answer:

The correct answer is - A) nuclear.

Explanation:

Most of the non-renewable sources of energy are fossil fuels that are formed by the thermal decomposition of dead organic matter for million years and are converted to lighter hydrocarbons that contain high electrostatic potential energy.

Burning is the process that breaks the hydrocarbons into water vapor and CO2 with high amount of energy. Coal, natural gas and biofuels all three are fossil fuels and nuclear products are not fossil fuel but radioactive elements.

Cory states the following argument about the evolution of aardvarks and anteaters.

"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."

Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.

Answer:

Transcription factors

Explanation:

This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.

Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.

In pea plants, peas can be green or yellow in color. Assume that green peas are dominant to yellow peas. Is it possible for two plants with green peas to produce any offspring with yellow peas?
vocabulary words to use in response: dominant allele, recessive allele, , heterozygous, genotype, phenotype

Answers

Answer:

No.

Explanation:

Turns out they have yellow peas because the yellow version, Y, is dominant over the recessive green version, y. Y always wins out over y: When a pea plant makes seeds, only one of its two copies of the color gene goes into the seed. So if you have two green pea plants, each can only pass a green version.

No.

If data for the growth of this bacterial population continued to be recorded, would the data point at 60 hours be above or below 37 million? Support your answer.

Answers

Answer:

Above 37 million

Explanation:

Explanation in picture below

Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

Thus, Bacterial population growth occurs geometrically or exponentially: in  each division cycle (generation), one cell produces 2 cells, then 4 cells, then 8 cells, then 16, then 32, etc.

The relationship shows that the average generation time is constant and  the growth rate of the bacterial population is proportional to the number of bacteria at any given time.

This relationship is valid only during the period when the population grows exponentially, ie. in  the logarithmic phase of growth. Therefore, graphs showing the growth of bacterial cultures are plotted as the logarithm of the number of cells.

Thus, Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

Describe an experiment used to prove that amino acids and sucrose go up and down the phloem.​

Answers

Answer:

By using carbon-14 in the experiment in order to prove the statement.

Explanation:

Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.
