Answer:

If a father has type A blood and the mother has type AB blood, they cannot have a child with blood type O, although depending on the father's genotype, they may not have children with a B blood type either.

Explanation:

Blood type is determined by the presence or absence of surface antigens A and B, which is genetically determined and establishes the pattern of inheritance.

Alleles that define the presence of antigens A and B are co-dominant, while the absence of antigens - as in blood type O - is a recessive trait.

The father with blood type A can have two genotypes, A|A or A|O, which raises 2 possible scenarios:

1. Father A|O with mother A|B

Alleles       A         O

A              A|A      A|O

B              A|B      B|O

In this case there is no chance of having a child with blood type O, 50% chance of having children with blood type A, 25% B and 25% AB.

2. Father A|A with mother A|B

Alleles        A        A

A               A|A     A|A

B               A|B     A|B

50% chance of having a child with blood type A and 50% with blood type AB. In this case there is no chance of having children with blood type O or B.

Explanation:

A eukaryotic cell contains membrane-bound organelles such as a nucleus, mitochondria, and an endoplasmic reticulum. Organisms based on the eukaryotic cell include protozoa, fungi, plants, and animals. These organisms are grouped into the biological domain Eukaryota.

Any organism which has a closed membrane for a nucleas is a eukaryotic cell.

(organisms who dont have a nuclear memebrane is called prokaryotic cell)

We have eukaryotic cells as we have nuclear membrane but a bactaria(a prokaryotic cell) doesnt have a nuclear memebrane and all of its nuclear substances are floating insdie it getting jumbled up.

Answer:

C. active transport, because protein pumps are needed to move substances against a concentration difference

Explanation:

There are two major types of transport in living cells namely: passive transport and active transport. The passive transport moves molecules down a concentration gradient and hence, do not need energy (ATP) to occur. However, on the other hand, ACTIVE TRANSPORT moves substances against their concentration gradient, thus, require energy input.

Active transport makes use of PROTEIN PUMPS to achieve this process. Hence, in this case where Alexis is using models of the cell membrane to compare the types of cellular transport. The model that shows a molecule entering through a protein pump is modelling ACTIVE TRANSPORT.

Answer/Explanation:

It results in offspring with genetic variation. 2 different mates must be used in sexual reproduction. This is because each person is different since cells are produced and combined differently in the original offsprings. If the two adults were exactly the same, the offspring would have the exact same cell traits. Likewise will be done for the offspring of the two adults. The genes may be similiar to the ones of the adults, but since combined it will not be an exact replica. In the long run sexual reproduction will result in an offspring with slightly different traits or genetic variation.

When hydrogen shares electrons with oxygen, the outermost shell of the hydrogen atoms are full with 2

electrons and oxygen’s valence shell is full with 8

electrons. Because the valence shells of these atoms are full, the atoms are stable.

Explanation:

Edge 2021

According to the electronic configuration, when hydrogen shares electrons with oxygen , hydrogen atom has 2 electrons and oxygen atom has 8 electrons.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

C. Paleozoic

Explanation:

Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.

We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.

Explanation:

Cellular respiration may be defined as the chemical process of breakdown of food in the cell with the liberation of energy in the form of ATP.

Photosynthesis is a chemical process through which green plants most photosynthetic algae synthesize their own food in the form of glucose. While nitrate absorption is the process through which nitrogen in the soil is significantly absorbed by the root of plants in form of nitrates.

Fermentation is initiated with the process of glycolysis, but it does not involve the upcoming two stages of aerobic cellular respiration such as the Krebs cycle and oxidative phosphorylation.

Cell Theory is a scientific theory proposed by Schwann in the year 1839. The cell theory has primary three postulates, which are used to describe the functioning of cells.

The correct answer is:

Option D. Cell parts such as chloroplasts are self-replicating.

The postulates of the cell theory are:

1. The cell theory states that all living cells arise from pre-existing cells.

2. The cells are the basic structural and functional unit of life.

3. The hereditary information is passed on from cell to cell, and the energy flows within the cell.

Answer:

Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quantity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.

Explanation:

hope this helps you out love!! <3

Answer:

weight of objects on EARTH> weight of objects on MOON

Explanation:

weight= mass * gravity

assuming both objects have the same mass, the environment with greater gravity will result in a greater weight

gravity of earth > gravity on the moon

so

weight of objects on EARTH> weight of objects on MOON

Projected values are only estimates. Can you think of either a natural or artificial factor that could increase or decrease the actual amount of wind energy the United States produces in the future?

Edmentum sample explanation:

Technological advancements in the future could lead to the production of higher-efficiency turbines, which could generate more electricity than originally predicted. Climate changes over time could affect wind speeds in a region, leading to higher or lower energy production.

The factors that would exert influence through the process of natural selection are a natural selection: diseases; artificial selection: and genetic engineering. The correct option is C.

The strongest survive through natural selection, and the most favored traits endure through evolution. Natural selection is the result of selection pressure on a population's frequencies of a specific allele. Evolution is the process through which, over an extended period of time, new sets of naturally selected organisms emerged.

Future technological developments might result in the creation of turbines with a higher efficiency, which might produce more electricity than was initially anticipated. Wind speeds in a place may alter as the climate shifts through time, which could result in increased or decreased energy output.

Therefore, the correct option is C. natural selection: diseases; artificial selection: genetic engineering.
