Answer:
P generation = TtRr × TtRr i.e both parents were heterozygote for both traits
Explanation:
This question involves two genes encoding the height and texture in pea plants respectively. The alleles for tall and smooth pea traits are dominant over the alelles for short and wrinkled traits.
According to this question, two plants are crossed to produce F1 offsprings as follows: 612 tall and smooth pea plants and 188 short and wrinkled pea plants.
First, we turn this derived number of offsprings into ratio by dividing by the smallest number (188)
612/188 : 188/188
3.25 : 1
Approximately; we can say this is 3 (tall and smooth) : 1 (short and wrinkled)
Based on this ratio, which was got by Mendel for his F1 offsprings when he crossed pea plants, the parental generation has a heterozygous genotype (TtRr).

Explanation:
Protein markers react with specific ______, which are proteins found in the immune system.
antigen
immunity
antibody
white blood cells
Protein markers react with specific antibody which are proteins found in the immune system.
Immune system generally produces antibodies to protect the body from foreign invaders (antigen) such as bacteria, viruses or pollen.
Proteins produced by the body immune system from the stores of immunoglobulin protein is known as Antibodies.
Antibodies works by recognizing and latching onto antigens in order to remove them from the body.
The correct answer is Protein markers react with specific antibody in the body.

which of the following statements about the cells of any multicelluar organisms is true
Answer The DNA in a cell is all the same
Explanation:
unlike eukaryotes prokaryotes do not contain a system of internal membranes. Any organelles, proteins, and genetic material are free - floating within the cytosol. Select the description below that correctly identifies how protein synthesis differs in prokaryotic and eukaryotic cells as a result of eukaryotic compartmentalization.
A. RNA processing occurs outside of the nuclear membrane in prokaryotes and inside it in eukaryotes.
B. Translation can occur before transcription in a prokaryote but not in a eukaryote.
C. Transcription and translation can occur simultaneously in a prokaryote but not in a eukaryote.
D. Ribosomes are needed for translation of mRNA in eukaryotes, but they are not needed in prokaryotes.
Answer:
The difference in protein synthesis in prokaryotic and eukaryotic cells, due to the compartmentalization of the latter, is that transcription and translation can occur simultaneously in a prokaryote but not in a eukaryote (option C).
Explanation:
Eukaryotic cells are characterized by a true nucleus, surrounded by a nuclear membrane. Since transcription occurs in the nucleus and translation for protein synthesis occurs in the cytoplasm, the former process occurs before the latter.
In prokaryotic cells the absence of a nucleus and compartmentalization system makes it possible for transcription of DNA into RNA and translation to occur simultaneously.
The other options are not correct because:
A. RNA processing, in both prokaryotes and eukaryotes, occurs in the cytoplasm.
B. Transcription precedes translation in all organisms.
D. Ribosomes are present and are necessary for protein synthesis in both prokaryotes and eukaryotes.

Elodia is a plant that lives in water. Like all plants, elodea can make its own food via photosynthesis. Oxygen is a gas produced during photosynthesis. Photosynthesis can only happen in the presence of light. To measure the rate of photosynthesis, a piece of elodia can be placed in an inverted test tube filled with sodium bicarbonate solution. Oxygen gas produced by photosynthesis will collect at the top of the tube. The experimental set up created by a student is shown above. What is the dependent variable in this experiment?
Answer:
Photosynthesis is the only dependent variable

What is the meaning of anatomical positions?Anatomical position, also renowned as standard anatomical position, implies to the body's position when it is standing and facing forward, with each of the arms hanging on side of the body along with palms facing forward.
The legs are parallel, with the feet flat on the floor and forward facing.
The lungs are basically two spongy, air-filled organs that are located on side of the chest in thorax. The trachea or windpipe transports inhaled air to the lungs via tubular branches known as bronchi.
It is attached to the sternum anteriorly and the vertebra posteriorly. The diaphragmatic surface (base) is concave and rests on the diaphragmatic dome; the right dome is also higher than the left dome due to the presence of the liver.

Hopetown is farther from the equator than kamina. Which location has colder air temperature and why
Answer:
Hopetown
Explanation:
The farther from the equator the colder the air temperature. This is because the equator is the point on planet Earth that receives the largest amount of solar energy, so the regions that are above this line are the warmest in the entire planet. The further away from the equator a region is established, the less solar energy it receives, which is why the poles are so cold. In this case, we can say that the Hopetown temperature is colder than the kamine temperature.

Is Subject B a male or female? _____________________________¬ How do you know? _________________________________________________________
Note about the question:
In the GIZMO program, you will be provided with 46 chromosomes that are not paired nor in order (box superior-right). According to the chromosome image shown below, you need to look for the correct chromosomes, pair them with their homologous, and place them in their correct spot to complete the karyotype.
Answer:
Subject B sex: FemaleJustification: The last pair of chromosomes are equally large, meaning that they are two X chromosomes (XX).Explanation:
Note: You will find the complete karyotype in the attached files.
A human cell has 46 chromosomes or 23 pairs of homologous chromosomes. 22 of them are somatic chromosomes or not-sex chromosomes. The last pair, number 23, is the only sex pair.
To know if an individual is a male or a female, you just need to see the last pair of chromosomes. Pair 23 is the sex pair.
Male: The pair is formed of a short chromosome (which corresponds to Y from the male parent) and a large chromosome (which corresponds to X from the female parent)---> XYFemale: The pair is formed of two equally large chromosomes. Each of them corresponds to X, one from the male parent and the other from the female parent). ----> XX3.
