please answer the question
its worth one mark so i need a short simple answer

Answer:

C

Explanation:

The brother has different alleles for the blood type gene than his sister does.  Blood type is inherited from parents like many other traits that can be displayed on a punnet square.  Depending on what the parents blood type alleles were, the brother and sister could have different blood types.  

A different number of chromosomes doesn't lead to different blood types, so D is wrong.  And A is incorrect because the number genes also does not affect blood type.  And I think the blood type genes are on the same chromosome, so B is wrong.  C is correct because blood type is inherited by alleles, and different alleles can cause different traits, such as blood types.  

Answer:

The term 'designer baby' refers to a baby that has been given special traits through genetic engineering. This is done by altering the genes of the egg, sperm, or embryo. These traits can, in theory, vary from lower resistance to diseases to even gender selection

Answer:

The conveyor belt moves at much slower speeds (a few centimeters per second) than wind-driven or tidal currents (tens to hundreds of centimeters per second). It is estimated that any given cubic meter of water takes about 1,000 years to complete the journey along the global conveyor belt

Explanation: Insulin is what keeps your blood sugar lower and sends signal when it needs glucose

Explanation:

This happened because in an open field the daisy's have more sun to do photosynthesis so yeah

Answer: Genetic variation within a species can result from a few different sources. Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. ... As a result, the tree-colored moths are more likely to survive, reproduce, and pass on their genes

Explanation:

Answer:

Chromosomes are positioned in the middle of the cell during metaphase.  

Explanation:

During metaphase, the centrosomes are at opposite poles or sides of the cell.  The spindle apparatus is formed and the nuclear membrane has dissolved.  The spindle fibers, also known as microtubules have lined up the chromosomes along the equatorial plate in the middle of the cell so each sister chromatid faces opposite directions.  The sister chromatids are still connected by the centromere, and this is the last time they are connected during this division.  The centromere is also where kinetochores assemble, and kinetochores are the sites of attachment for microtubules to pull the sister chromatids apart.  They are important for the cell to be able to divide.  

Answer:

Krebs cycle, tricarboxylic acid cycle.

Explanation:

Cellular respiration is what cells do to break up sugars to get energy they can use. ... Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain.

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules[1] or nutrients into adenosine triphosphate (ATP), and then release waste products.[2] The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen,[3] are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.

Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent providing most of the chemical energy is molecular oxygen (O2).[1] The chemical energy stored in ATP (the bond of its third phosphate group to the rest of the molecule can be broken allowing more stable products to form, thereby releasing energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transport of molecules across cell membranes.

Answer:

D

Explanation:

Key points:

- Cells have a variety of mechanisms to prevent mutations, or permanent changes in DNA sequence.

- During DNA synthesis, most DNA polymerases "check their work," fixing the majority of mispaired bases in a process called proofreading.

- Immediately after DNA synthesis, any remaining mispaired bases can be detected and replaced in a process called mismatch repair.

- If DNA gets damaged, it can be repaired by various mechanisms, including chemical reversal, excision repair, and double-stranded break repair.

Answer:

yes, but by gas you mean oxygen right?

Explanation:

Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Answer:

There are a few differences between plant cells and animal cells, such as size, shape, energy storage, proteins, differentiation, growth, the cell wall and plenty more!

Explanation:

Hope this is helpful. If you need more differences or need me to explain let me know!!

Answer:

1)When the oxygen level is low, carbohydrates break down for energy and produce lactic acid. Lactic acid levels rise with strenuous exercise or other conditions - such as heart failure, severe infection (sepsis), or shock - which reduces the flow of blood and oxygen throughout the body.

2) no gender differences in resting or peak blood lactate concentrations, nor in the rate of blood lactate removal of young adult men and women with similar aerobic fitness level expressed as ml.kg FFW1

Answer:

Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated.

Embryonic stem cells are derived during early development at the blastocyst stage and are pluripotent, meaning that they can differentiate into any cell type. In contrast, adult stem cells are rare, undifferentiated cells present in many adult tissues.

Answer:

so i belive ur talking about the corona vaccinations so my answer is below! :D

Explanation:

if you get vaccinated, you are helping yourself and other people because it is most likely that you wont get corona if u have a vaccine. When you dont get corona that means that there are less people dying and you will reduce the level of deaths because ur not gonna get corona and give it to someone else. Once you get the vaccine you still have to be protected and wear a mask when you go outside just in case to protect your self and someone elses life. So, thats why ur vaccination status affects more people than just you. :D

also i just realized that you might not be talking about the corona vaccinations and u can be talking about the normal vaccines but the paragraph that i just wrote can be meant for normal vaccines as well :)

Answer:

The correct answer is - Archaea.

Explanation:

Archaea is one of the three domains of life other than bacteria and eukarya. Archaea are prokaryotic organisms that are unicellular and present in very extreme conditions like salt environments or extreme heat.

Archaea used to be placed with bacteria but due to some closeness with the characteristic of eukarya as well as bacteria, it is placed as a separate domain. It lacks nuclei and has a cell wall in its cell.

Answer:

Increasing the membrane area also increases the number of ATP and NADPH generating sites

Explanation:

Photosynthesis occurs in the chloroplast, more precisely in the membranes of the thylakoids that form stacks of disks called grana. A mature chloroplast may have 20 to 60 grana. In these membranes, there are photosystems, which are structural units of pigment-protein complexes that convert light energy from the sun into chemical energy stored in ATP and NADPH. A thylakoid may contain thousands of photosystems. In consequence, increasing the membrane area also increases the number of photosystems required for the synthesis of ATP and NADPH.
