Answer:
The correct answer is - Phase I.
Explanation:
Clinical phase are group of stages in which scientists or researchers conduct various experiments with a health intervention to get enough evidence for a process to use as a medical treatment. Clinical research is conducted on medical devices, drug candidates, and vaccine candidates.
In the phase I, in this phase intervention takes place in human subjects. These subject usually observed until several half-lives of the drug have passed. This phase is designed to assess the tolerability, pharmacokinetics, safety (pharmacovigilance), and pharmacodynamics of a drug

punto de vista sobre la ley de mendel
Answer:
Las leyes de Mendel son leyes que describen la herencia de rasgos hereditarios. Las leyes forman la base de la genética clásica. Asumen que cada individuo posee dos alelos para el mismo rasgo y los recibe al azar de los cuatro alelos diferentes de los padres. El fenotipo (apariencia física) del individuo depende de cuál de los dos alelos es dominante y cuál es recesivo. Dado que los individuos pueden transmitir ambos alelos a su descendencia, la descendencia incluye tanto individuos con fenotipo dominante como recesivo.

List the negative impacts of human activities on vegetation?
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.

how would hemoglobin content differ in a person living in philadelphia compared to someone living in denver
Answer:
The correct answer is - the difference in altitudes.
Explanation:
The hemoglobin in the person of Denver who lives at a higher altitude than the person who lives in Philadelphia will be much higher. This is due to the fact that at higher elevation or altitude atmospheric pressure decreases that causes hemoglobin to stick to the RBCs and that results in less oxygen level in the body.
To compensate for this low level of oxygen levels hemoglobin content need to be higher in people living at a higher elevation.

somebody help. . ways of propagation of plant materials for planting.
Answer:
These seven methods include: seed propagation, cutting, layering, division, grafting, budding, and tissue culture technique.
Explanation:
The major methods of asexual propagation are cuttings, layering, division, budding and grafting. Cuttings involve rooting a severed piece of the parent plant; layering involves rooting a part of the parent and then severing it; and budding and grafting is joining two plant parts from different varieties.
Mammals are a large group of animals that includes humans, apes, dolphins, bears, bats, cats, and much more. Which statement can be made about this information? All mammals use echolocation to find food. Some mammals use echolocation to avoid obstacles. All mammals use walking as their primary means of transportation. Some mammals need to find food to survive.
Answer: B
Explanation:
Just did the test
The statement that can be made about the information is: "Some mammals need to find food to survive."
What are Mammals?Mammals are a diverse group of animals that are found all over the world and come in many different shapes, sizes, and types.
All mammals share certain key characteristics, including the fact that they are warm-blooded, have hair or fur, and feed their young with milk produced by their mammary glands.
While the information given in the first sentence provides a list of mammals, it does not provide any information about their specific behaviors or characteristics, such as the use of echolocation or means of transportation.
However, the statement that "some mammals need to find food to survive" is true for all mammals, as food is a basic necessity for the survival of all members of this animal group.

It is impossible for sperm to be functional (able to fertilize the egg) until after ________. Group of answer choices
Answer:
The answer is "they undergo capacitation"
Explanation:
Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes. For a sperm cell to fertilize an egg, it takes approximately 24 hours. The surface of the egg changes as the sperm penetrates the egg, therefore no sperm is allowed within. The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.
Which of the following do all living things share?
A. The same shape
B. The same organs
C. The need to breathe
D. The same elements
Answer:
D.
Explanation:
Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy
A meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm, how many chromosomes will be in the zygote
Answer:
47 chromosomes
Explanation:
Meiosis is a kind of division that reduces the chromosome number of the daughter cells by half i.e. 2n - n. It occurs only in reproductive cells to produce sex cells or gametes. In humans, meiosis occurs to produce gametes (egg and sperm) that have 23 haploid chromosomes.
N.B: Somatic human cells have 46 chromosomes
According to this question, a meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm i.e. sperm with 23 chromosomes. A zygote that posseses (23 + 24) = 47 chromosomes will be produced.

Question in the photo
Answer:
C
Explanation:
From reading what the process is, I think the answer should be C. The definition always says that you get energy from a chemical reaction and the products are CO2 and water. That can only mean that you have a hydrocarbon burning.
Chemically it looks like
C6H12O6 + 6O2 ====> 6CO2 + 6H20

PLEASE HELP!!! Give two forms of evidence for evolution that can be found in the fossil record (where animals have changed from simple to more complex.)
Answer:
Forms of fossil records can inlude the carcasses of animals and the structure of plants. These records can compare the advancements of creatures over a long period of time.
Explanation:
The further an animal or plant is burried underneath the soil, it is most likely that it lived much longer ago than a layer above it. The theory of evolution suggests that animals are always changing and adapting to their surroundings. For instance, millions of years ago, a dog like mamal existed but over time they grew accustomed to the water, developing fins flippers and eventually developed features similar to what we expect in whales today.
Plants, on the other hand, may have been much larger than the size they are today due to the excess of oxygen present in the atmosphere. Therefore, when they are fossilized scientists can realize that plants have come a long way in the tree of evolution.
