Type of cell division that is occurring in the cell in the diagram
Answer:
There is no diagram but the cell division happens in stages. PMAT is a way to remember them. prophase, metaphase, anaphase, and telophase. This all takes place in Mitosis. Mitosis is the division of cells to make more *identical* cells, (skin cells, stomach cells). But Miosis is the making and division of sperm cells *not Identical* (sperm, and egg cells) are made in this phase.

Given the following cross TtYyRr x TtyyRr (T = tall; t = short Y = yellow; y = green R = round; r = wrinkled), what proportion of offspring would be expected to be short plants with round, green seeds. Write your answer as a reduced fraction - e.g. 1/2 proportion is
Answer:
3/32 ttyyR-
Explanation:
Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual
Parentals) TtYyRr x TtyyRr
Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)
TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)
We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:
Shot → ttRound → RR or RrGreen → yy⇒ Parent one can provide gametes tyR and tyr
⇒ Parent two can provide gametes tyR and tyr
(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =
2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =
1/32 ttyyRR + 2/32 ttyyRr =
3/32 ttyyR-
The branch of science which deals with the gene and inheritance is called biology.
The correct answer is 3/32.
When a parent has 3 characters and crosses with other parents which have a 3 character is called a trihybrid cross.
In this question, the genotype of the parent is given as follows:-
Mother - TtYyRrFather - TtyyRrThe gametes formed by the parents is as follows:-
TYR, TYr, TyR, Tyr, tYR, tYr, tyR, tyr is gamete of motherTYR, TYr, TyR, Tyr, tYR, tYr, tyR, tyr is gamete of father.According to the law of inheritance it stated that the each gamete can fused with any gamete to increase the chances of variation.
Hence, after the crossing the number of offspring will form is 32.
Therefore the offspring which has a short plant with a round green seed is 3/32.
Hence, the correct answer is 3/32.

Let's start with a ham and cheese sandwich with lettuce and pickles. As I bite into my sandwich the teeth are present for mastication to begin the process of mechanical digestion and the saliva begins to mix with my food where salivary amylase is present and starts the digestion of the starchy bread. What happens next? (Think about the carbohydrates, proteins and fat in our sandwich
Answer:
Explanation:
After amylase act on carbohydrates, the chyme pass through the oesophagus down to the dudoneum in the small intestine. Amylase also continue to break it down into disacharrides and enzymes like maltase, sucrase and lactase are released to further break it down into maltose, sucrose, and lactose then finally glucose, a way it can be absorbed easily by the epithelial walls.
The digestion of lipids and protein begin in the dudoneum of small intestine.
Trypsin act on protein and break it down to peptides. Peptidase is then released and break it to single chain peptides bond. In the small intestine, dipeptidases break it down into amino acids easily absorbed by the epithelial walls.
The bile in the gall bladder produce enzyme called lipases which breakdown lipids and make it to undergo emulsification.

Describe the metabolic pathways in the monarch butterfly that take advantage of milkweed nectar to convert it into an energy currency.
Answer:
Metabolic pathways in monarch butterflies are as follows:
GlycolysisKreb's cycleOxidative phosphorylationExplanation:
They convert sugar which they obtain from nectar into fats that they store as source of energy. Monarch have a little layer of fatty tissues which aid in conversion of Sugar in to fat.
They consume the stored fat during reproduction. A lot of fat is eventually converted to eggs and some of it is used to provide energy just to sustain the reproductive butterflies.
During winter season, when their metabolic is low they consume energy by converting stored fat into sugar called Trehalose. The conversion of fat also releases little water which help them to survive during winter.
1) Glycolysis:
Glucose is phosphorylated by hexokinase enzyme to give glucose-6phosphate. This glucose-6-phosphate enters into glycolysis and is broken down into two molecules of pyruvate in a series of ten reactions. During glycolysis net two molecules of ATP are synthesised per glucose molecule. Moreover, two molecules of NADH+H+ are also synthesised. In aerobic organisms like monarch butterfly the pyruvate is again oxidised to give acetyl-CoA in the mitochondria. The enzyme responsible for this oxidation is Pyruvate Dehydrogenase Complex. This reaction occurs in the mitochondrial matrix. Here one CO2 molecule is removed from the pyruvate and one NADH is produced.
2. Kreb's Cycle:
The acetyl-CoA formed enters into the Kreb's cycle by condensing with oxaloacetate. In Kreb's cycle acetyl-CoA is completely oxidised to give carbon dioxide in eight enzymatic reactions. During Kreb's cycle NADH, FADH2 and one molecule of GTP is produced and oxaloacetate is regenerated to continue the cycle.
3. Oxidative Phosphorylation:
The NADH produced in the glycolysis and Krebs cycle and FADH2 produced during Krebs cycle are now oxidised to generate proton gradient across the inner mitochondrial membrane. This gradient is generated when the electrons from the reduced NADH and FADH2 are transported in the electron transport chain(ETC), and are finally accepted by the oxygen.
When the electrons are picked up by the complexes of the ETC they pick protons from the matrix. When the electrons are transferred to next complex the protons are transferred to the inter-membrane space. In this way a proton gradient is generated across the innner membrane of the mitochondria.
This proton gradient is used by the complex V of the ETC. This complex is the enzyme ATP Synthase. This enzyme complex is located in the inner mitochondrial membrane. When the protons flow back from the inter-membrane space into the matrix along the concentration gradient , they move through the channel in the ATP Synthase Complex. When these protons flow through this complex it catalyzes the phosphorylation of ADP to give ATP, the energy currency.
The fructose component of the sucrose is first converted into glycogen and then broken down to give glucose-1-phosphate, which enters into glycolysis.
Sucrose cannot enter the pathway of glycolysis as such. It is first hydrolysed to glucose and fructose as described above along with the path way.

The complex structures of DNA and protein found in the cell nucleus are mitochondria. nucleoplasm. histones. nucleases. chromosomes.
Answer:
chromosomes
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
The complex structures of deoxyribonucleic acid (DNA) and protein found in the cell nucleus are generally referred to as chromosomes.
In sexual reproduction, the chromosomes from parents are found in the cell nucleus and are comprised of deoxyribonucleic acid (DNA), histone proteins, etc. Thus, they are used to store genetic informations in living organisms.
Basically, the human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.

Which of the following is MOST directly involved in the motility and intercellular signaling in T-cells: W) filamentous actin X) 200-nanometer myosin fibrils Y) cathepsin-myosin complexes Z) microvilli
Answer:
W) filamentous actin
Explanation:
T cells are a type of white blood cells (leukocytes) that play a fundamental role in the immune system by determining the specificity of the immune response to specific antigens. In T cells, the remodeling of the actin cytoskeleton is critical for the movement of these cells through different tissue environments and for adjusting their behavior during the scanning of antigen-presenting cells. The actin cytoskeleton acts as a physical platform for intracellular signaling events that occur at the immunological synapse formed between a T cell and an antigen-presenting cell, thereby contributing to T cell activation.
How does an ATP molecule release
energy for cells?
A. changing the base, adenosine, to guanine
B. breaking the bond between the 2nd and 3rd
phosphate
C. removing the ribose sugar
Answer:
The correct answer is - B. breaking the bond between the 2nd and 3rd.
Explanation:
ATP molecule is known as cellular currency as it provides energy for cellular functions. ATP released energy when one phosphate group is removed or eliminated by breaking a phosphoanhydride bond. The rebreaking of this bond and removal is known as hydrolysis, and ATP is converted to adenosine diphosphate (ADP).
Breaking the bond between the 2nd and 3rd phosphate groups provides a very high amount of energy. There is also additional energy released when phosphate is removed from ADP to form adenosine monophosphate (AMP).
What is the albedo effect?
Do you think the earth is warming up?
Answer: Astronomers define the reflectivity of an object in space using a term called albedo. This is the amount of electromagnetic radiation that reflects away, compared to the amount that gets absorbed.
Explanation: But to answer the "Earth warming up" question, I'd have to say that for over millions of years, Earth's climate has warmed up and cooled down many times. However, today the planet is warming much faster than it has over human history. Global air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the last century. However, other evidence suggests that the period of 2,000 to 3,000 million years ago was generally colder and more glaciated than the last 500 million years.
So, yes I do believe that the Earth is warming up but not to explode.

name a disorder that is a result of shortage of proteins in children
Answer:
A disorder that is a result of shortage of proteins in children is Kwashiorkor
Explanation:
Kwashiorkor is a severe form of malnutrition. It's most common in some developing regions where babies and children do not get enough protein or other essential nutrients in their diet. The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin (oedema). (Source: Kwashiorkor - NHS)
Hopefully this helps.
Kwashiorkor is a serious condition that can happen when a person does not consume enough protein. Severe protein deficiency can lead to fluid retention, which can make the stomach look bloated.
Kwashiorkor is most common in children, especially if they do not have access to adequate nutrition soon after they stop breastfeeding. If a child experiences kwashiorkor, they need immediate medical attention.
Other terms for kwashiorkor include:
protein malnutrition
malignant malnutrition
protein-calorie malnutrition
