Answer 1

Accualy some do, but that's a little rare, so I'm guessing because each child gets some of there mom and dad's to genetics, one child might get some of there mom's but more of there dad's and the other might get some of there dad's and more or there mom's..? not sure if that makes any sense-

If an individual has the genotype Bb, what alleles can it pass on to its
offspring?
A. Only B
B. Neither B norb
C. Either B or b
D. Only b

Answers

The answer is C. Either B or b

If a person possesses the genotype Bb, either the B or the b alleles can be passed on to their progeny. So, the correct option is C.

What is Genotype?

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries inside a specific gene or genetic region are also referred to as the genotype.

The term "genotype" relates to an organism's whole gene pool, or, in other words, the genetic make-up of that creature. The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb could be used to denote a certain gene variant.

If a person has the genotype Bb, as in the example above, then either the B or the b alleles can indeed be passed on to their progeny.

Therefore, the correct option is C.

In periods of hot, dry weather, the small pores (holes) on the surface of leaves of most plants will close in order to reduce water loss. When these pores are closed, carbon dioxide is restricted from entering the leaf. As a result, what product will also decrease? a. Cellular respiratory b. Water c. Glucose d. Carbon dioxide

Answers

c.Glucose

The stomata of plants will close during hot and dry day. This cause a decrease in concentration of carbon dioxide and increase in oxygen concentration in the plant. Photorespiration occur.

As carbon dioxide in photosynthesis is used to produce glucose molecules, the production of glucose molecule will decrease.

A motorcycle accelerates 3 m/s2 due to a force of 330 N. What is the mass of the motorcycle? Mass of motorcycle = _____ kg

Answers

Answer:

110 kg

Explanation:

Given

Acceleration (a) = 3m/s²

Force (F) = 330N

Required

Determine the mass of the motorcycle

This question is an illustration of Newton's second law and will be solved using:

Force = Mass * Acceleration

F = m * a

This above implies that force applied on the motorcycle is a product of its mass and its acceleration

Substitute values for F, and a

330N = Mass * 3m/s²

Make Mass the subject

Mass = 330N/3m/s²

Mass = 110kg

Hence, the calculated mass of the motorcycle is 110kg

Answer:

110

Explanation:

how do photosynthesis and cellular respiration form a cycle?​

Answers

Answer:

The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Explanation:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Which best describes a codon?
a cell structure that gives the master instructions for an organism
a segment of DNA that is the basis of heredity in organisms
the sequence of three bases that codes for a specific amino acid
the basic unit of structure and function of all living things

Answers

Answer: the sequence of three bases that codes for a specific amino acid

Explanation: I took the test and i got this answer correct so i hoped this helped!!

Codons are generally a sequence of three bases in the DNA and RNA that codes for specific amino acids. So option C is correct.

What is a genetic code?

A genetic code is a set of information that helps to convert the genetic information stored inside the genetic material into a defined sequence of amino acids called a protein.

Though the DNA has nucleotide sequences that contain information for producing the proteins, the DNA cannot directly synthesize the proteins. It is first converted to mRNA in order to be translated into a specific protein.

There are in total 64 codons, out of which 61 code for specific amino acids while the remaining three codons are known as stop codons and are used in terminating the process of translation of proteins.

En un experimento un floricultor cruzó plantas de flores púrpuras con plantas de flores blancas, los resultados obtenidos durante la primera generación fueron de un 100% de flores púrpuras, y en la segunda generación un 25% de flores serán de color blanco y el resto de color púrpura. Los genotipos de los parentales (P)

Answers

Answer:

Los genotipos de los parentales son:

- pp (homicigota dominate con flores púrpura)

- bb (homocigota recesivo con flores blancas)  

Explanation:

Alelos:

p: púrpura y b: blanco

Genotipos parentales:  

- pp: homocigota dominante (flores púrpura)

- bb: homocigota recesivo (flores blanca)

Cruzamiento parental: pp X bb

F1: 100% pb  

Cruzamiento F1: pb X pb

F2: 25% pp (flores púrpuras), 50% pb (flores púrpuras) y 25% bb (flores blancas)

En este caso, el alelo que determina el color púrpura es dominante sobre el alelo que determina el color blanco. Es por esta razón que en la F1 todas las plantas heterocigotas exhiben un fenotipo con flores púrpura. En la F2 la proporción fenotípica será 1:2:1 (1 homocigota dominante, 2 heterocigotas y 1 homocigota recesivo), mientras que la proporción genotípica será 3:1 (3 plantas con flores púrpuras y 1 planta con flores blanca).

How might retaining too much heat be a disadvantage to an organism?

Answers

One disadvantage of having a large surface area to volume ratio is the heat loss. An organism that has larger surface area has high rate heat gain and heat loss. Therefore they need to eat or acquire nutrients faster in order to sustain life.

Excessively heat can damage the plasma membrane and disrupt subcellular structures such as membrane proteins and enzymes.

What are subcellular structures?

The following are the primary subcellular structures found in animal cells: The nucleus is where genetic material is stored.

Cell membranes regulate what enters and exits the cell. Mitochondria: aerobic respiration site. Ribosomes are the sites where proteins are synthesized.

Protein denaturation occurs at high temperatures and affects protein folding, bonding, and other types of behavior.

Furthermore, membrane proteins play an important role in cell function regulation. If these are disrupted, the system will be unable to maintain homeostasis, or a stable internal environment.

Heat can damage the plasma membrane and disrupt subcellular structures like membrane proteins and enzymes.

Thus, this way, retaining too much heat can be a disadvantage to an organism.

This is from gizmos if you know this pls help me out

Answers

Answer:

The antidote entered into Jared's cell and targeted the cyanide that was disrupting his Electron Transport Ch...

Explanation:

The antidote entered into Jared's cell and targeted the cyanide that was disrupting his Electron Transport Chain. The antidote changes the cyanide into a molecule called thiocyanate. Jared’s body can now remove this molecule through his excretory system. As the cyanide is removed, electrons can now leave the ETC by reacting with O2 to make water. His ETC can now get new electrons from NADH this then means he is able to move more H+ into the inter-membrane space. Jared’s cells can now make ATP again.

The antidote binds cyanide. This binding impedes cyanide to inhibit the cytochrome oxidase action. As the cytochrome reactivates, electron transport reactivates as well, and ATP is synthesized again.  

---------------------------------------------------------------------

Ion cyanide inhibits cellular respiration by binding to the ferric ion of cytochrome oxidase and blocking the electron transference.

Because the electron transporter chain is interrupted, there is no ATP production, and muscles do not get enough energy.

The antidote enters Jared's cells and targets cyanide.

When the antidote meets cyanide, it binds to this last one and blocks its effect on cytochrome oxidase.

As cyanide can no longer bind the ferric ion of cytochrome oxidase, the enzyme remains active, and the electron transport is reactivated.

As electrons move along the chain, protons are pomped to the intermembrane space.

ATP production reactivates again as well because the proton gradient is used to produce ATP molecules.

Homeostasis is maintained by which of the following organ systems in humans?
A. Multiple organ systems working together
B. The muscular system
C. The endocrine system
D. The nervous system

Answers

A. Multiple organ systems working together

Explanation:

All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.

What would happen if the sedimentary rock was exposed to energy from the sun and then millions of years later to energy from Earth’s interior?

Answers

Answer:

They would become igneous rocks

Explanation:

If originally, sedimentary rocks are exposed to energy from the sun, no changes will occur to them.

One will hardly spot any difference in their mineralogical composition as such.

The temperature of the sun does not any significant alteration on earth materials. The heat from the interior has a very significant effect on rocks, especially sedimentary rocks. Heat from the interior can reach a staggering 6000°C which is more than enough to cause a metamorphic change in a body rock. In fact, at this temperature, igneous rock will be produced from the sedimentary rock.

Igneous rock will be produced from the sedimentary rock if the sedimentary rock was exposed to energy from Earth’s interior for millions of years.
