Please help me!! what is the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy?
Answer:
3/16
Explanation:
This question involves two genes coding for pea shape and pea color. The alleles for yellow color (Y) and round seeds (R) are dominant over the alleles for green color (y) and wrinkled seeds (r).
In this cross between two heterozygotes: RrYy × RrYy, the following allele combinations are produced in the gamete of each parent: RY, Ry, rY and ry. Using these gametes in a punnet square (see attached image), the following offsprings are produced:
9/16 of Round, yellow offsprings (R_Y_)
3/16 of Round, green offsprings (R_yy)
3/16 of Wrinkled, yellow offsprings (rrY_)
1/16 of wrinkled, yellow offsprings (rryy)
Hence, the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy is 3/16.

Which of the following scenarios can be classified as a negative feedback loop?
a increase in blood pressure to reduce heart rate
b increase in testosterone to help increase a fight-or-flight response
c increase in oxytocin caused by increased contractions
d increase in platelet production to help increase blood clotting
Answer:
The scenario that can be considered an example of a negative feedback loop is increase in platelet production to help increase blood clotting (option d).
Explanation:
Negative feedback loop is what occurs when a change occurs in the body, producing a response that decreases or stops that change, with the intention of maintaining homeostasis.
When there is a wound that produces bleeding, a series of mechanisms are activated, the coagulation cascade, which promotes the release of factors that allow the formation of clots. The increased release of platelets implies negative feedback because it helps to stop the change that occurs in the body, the loss of blood, through the formation of clots.
One thing that can cause confusion is the fact that this response also involves positive, though limited, feedback that promotes the production of clotting factors and platelets to increase clot formation. What really happens is that the positive feedback promotes the general feedback, which is the negative feedback: clot formation to stop the bleeding, restoring homeostasis.
The other options are not correct because:
a. Increase in blood pressure to reduce heart rate is not possible.
b. In the fight and flight response the hormones involved are cortisol and adrenaline, not testosterone.
c. Increased oxytocin in response to uterine contractions is positive feedback.
Which numbered organelle produces ATP during cell respiration?
The mitochondria produce ATP during the process of aerobic respiration.
What are mitochondria?
Almost all eukaryotic cells (cells with clearly defined nuclei) have a membrane-bound organelle called a mitochondrion, whose main job is to produce huge amounts of energy in the form of adenosine triphosphate (ATP).
Mitochondria normally have a circular to oval shape and can be anywhere from 0.5 to 10 m in size. In addition to providing energy, mitochondria also create heat, control cell growth and death, and store calcium for cell signaling functions.
As an illustration, human erythrocytes (red blood cells) do not have any mitochondria, but liver cells and muscle cells may have hundreds or even thousands of mitochondria. The oxymonad species Monocercomonoides is the only eukaryotic organism that is known to be mitochondria-free.
Because they contain a unique genome, two separate membranes, and binary fission as a method of reproduction, mitochondria differ from other cellular organelles and may have evolved from prokaryotes (single-celled organisms).
Therefore, the organelle producing the ATP is the mitochondria.

During photosynthesis, plants produce ___ and oxygen from the ___ of solar energy, water, and carbon dioxide.
Answer:
1. Glucose
2. Conversion
Explanation:
During photosynthesis, plants produce glucose and oxygen from the light of solar energy, water, and carbon dioxide. This process is called photosynthesis.
What is photosynthesis?Photosynthesis is a process that takes place in green plants because they have chlorophyll pigment. Chloroplast is the organelle that is present in green plants. This organelle has chlorophyll pigment that carries out the photosynthesis process.
In photosynthesis, water is taken from the soil, carbon dioxide is taken from the atmosphere, and with the help of sunlight, glucose and oxygen are formed in the chloroplast. Due to this, plants are called producers.
Photosynthesis releases oxygen into the atmosphere, which is required by all living organisms. Organisms take in oxygen and release carbon dioxide into the environment. This is called the respiration process.
In the grassland ecosystem, the plants do photosynthesis. In the ocean's ecosystem, phytoplankton do photosynthesis. Different consumers depend on these producers for food.
Hence, plants produce glucose and oxygen from solar light energy, water, and carbon dioxide.

When studying cells structure using a microscope the smallest unit of measurement
commonly used to describe findings is the nanometre. Explain why.
Since a nano-metre is the most accurate unit for working with the extremely small cell structure (the majority of cell organelles are between 1 and 1000 nano meters)
Why is it important to measure cell size?The fundamental functions of a cell's physiology, such as flux across membranes, depend on the size of the cell as a whole, which is one reason why cell size matters. Changes in the volume or surface area of a cell will therefore have a significant impact on the metabolic flux, biosynthetic capacity, and nutrient exchange.
Which tool is used to see the smallest units in cells?Under a light microscope, smaller cells are clearly visible. Even internal cell structures like the nucleus, mitochondria, and chloroplasts can be seen. An image is magnified by a system of lenses in light microscopes. Micrometers are used to measure the cell's size. Human red blood cells have a diameter of 7.0 micrometers, while the smallest cell known as Mycoplasma is 0.3 micrometers. Animal and plant cells typically range in size from 10 to 30 microns.

How is cellular respiration dependent upon an animal's respiration rate?
Answer:Every cell in an animal requires oxygen to perform cellular respiration. Cellular respiration is the process by which animals take in oxygen and exchange it for carbon dioxide and water as waste products.
Explanation:
Every cell in an animal requires oxygen to perform cellular respiration. Cellular respiration is the process by which animals take in oxygen and exchange it for carbon dioxide and water as waste products.
Cellular respiration is dependent upon an animal's respiration rate because
respiration rate depends on the amount of oxygen inhaled and available to
break down food(cellular respiration).
The oxygen inhaled by animals enter into the cells of the body through the
blood. Carbon dioxide formed in cells is then replaced by the oxygen.
The less the amount of oxygen inhaled during respiration , the less the
cellular respiration that takes place in the animal and vice versa.
The above analysis shows that respiration rate and cellular respiration have
a direct relationship which explains why they are dependent on each other.

C. reduces chromosome number by half, produces diploid cells
D. reduces chromosome number by half, produces gametes
The phrase that best describes the function of meiosis reduces the chromosome number by half and produces gametes. The correct option is D.
What is meiosis?Meiosis is the division of gametic or sex cells. This process occurs during reproduction. It completes in eight stages. It is divided into two parts. Meiosis I and meiosis II.
After meiosis, I, the daughter cells move directly into meiosis II without going through interphase or DNA replication. With the exception of the halving of the number of chromosomes, meiosis II resembles mitosis.
Because it contains the chromosomes of both parents, to make the number of chromosome-specific to humans, its numbers of chromosomes is reduced to make it 46.
Therefore, the correct option is D. reduces the chromosome number by half and produces gametes.

e. coli are grown on a medium containing lactose. once glucose is added to the medium, the bacteria stop fermenting lactose
The lac operon is an operon required for the transport and metabolism of lactose in E.coli. When lactose is introduced to the increased medium, the lac genes are expressed due to the fact allolactose binds to the Lac repressor protein and maintains it from binding to the lac operator. Allolactose is an isomer of lactose. Small quantities of allolactose are shaped when lactose enters into E. coli. allolactose binds to the repressor protein and reasons the conformational change. As a result of this, the repressor can no longer bind to the operator area and falls off. RNA polymerase can then bind to the promoter and transcribe the lac genes. After some time, when the level of lactose decreases as it is metabolized using enzymes, it causes the synthesis of the repressor from the regulator gene. This repressor binds to the operator gene and prevents RNA polymerase from transcribing the operon and the transcription is stopped. This type of law is acknowledged as negative regulation.
Allolactose is a disaccharide comparable to lactose. It consists of the monosaccharides D-galactose and D-glucose linked thru a β1-6 glycosidic linkage alternatively of the β1-4 linkage of lactose. It may additionally occur from the occasional transglycosylation of lactose through β-galactosidase.
