how does the antigen-antibody complex protect the body

Answers

Answer 1

Answer:

Explanation:

the antibodies destroy the antigen (pathogen) which is then engulfed and digested by macrophages. White blood cells can also produce chemicals called antitoxins which destroy the toxins (poisons) some bacteria produce when they have invaded the body.

what happens during interphase?the nucleus grows to its full cell grows to its full nucleus divides into two cell divides into two cells.

Answers

During interphase, which is the longest phase of the cell cycle, the cell undergoes several crucial processes in preparation for cell division. It can be divided into three main stages: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

In the G1 phase, the cell grows in size, performs its regular metabolic activities, and prepares for DNA replication. The nucleus is intact and not dividing during this stage.

The S phase is characterized by DNA replication, where the cell's genetic material is duplicated. Each chromosome forms two identical sister chromatids that remain attached at the centromere.

The G2 phase follows DNA replication and is focused on cell growth and preparation for division. The cell continues to synthesize proteins, increase in size, and check for any DNA damage or errors.

Therefore, during interphase, the cell grows in size, performs necessary metabolic activities, replicates its DNA, and ensures proper preparation for subsequent cell division.

Answers

Eukaryotic repressors bind to specific DNA sequences and prevent transcription, just like their prokaryotic counterparts. Hence (b) and (c) are true and (a), (d) and (e) are false.

A true statement is that enhancer sequences can be found thousands of base pairs after the transcription start point. DNA base pairs make up enhancer sequences. False: Enhancer sequences modify transcription levels directly. Levels of transcription are always increased by transcription factors. The whole enhancer sequence is where transcription factors bind. Enhancer regions, in addition to promoter sequences, aid in enhancing transcription. Enhancers may exist upstream, downstream, inside a gene, on different chromosomes, or anywhere in between. Enhancer areas are where transcription factors bind to promote or inhibit transcription. Both transcriptional activators and repressors control gene expression in eukaryotic cells.

State and describe three major factors that lead to reef erosion.

Answers

Reef erosion has occured due to overfishing, pollution and unsustainable forms of tourism, among other reasons.

Due to the increasing pollution, there are a number of toxicants and pollutants released in the air and water. As a result, there can be an increase in the growth of algae and other organisms that can hinder the growth or destroy the reefs.

Overfishing is also harmful to the coral reefs. Fishing nets left as debris cause entangling of the live corals which tears them away from their bases. The anchors used for fishing also can break and ruin coral reef colonies.

Increased tourism also adversely affects coral reefs. Irregukarized building of hotels and tourist places, irresponsible business management as well as irresponsible behavior of tourists also poses a threat to reefs.

What is a Population?

A population may be defined as a group of individuals belonging to the same species living in the same area at a definite time. The size, density, birth rate, death rate, and abundance, are some characteristics of a population. These characteristics of the population are known as demographic factors.

According to the context of this question, the axis of the graph is increasing very rapidly. It determines the rate of population towards rapid growth. The growth of any population depends on various factors such as space, food, resources, mating partners, availability, etc.

normal components and a messenger rna (mrna) with the sequence 5′−uuuugccauguuugugcu−3′. what is the sequence of the radiolabeled peptide renata produces?

Answers

The sequence of the radiolabeled peptide produced by Renata can be determined by translating the mRNA sequence using the genetic code. The genetic code is a set of rules that specifies how the sequence of nucleotides in mRNA is translated into the sequence of amino acids in a protein. Each three-nucleotide sequence, called a codon, corresponds to a specific amino acid or a stop signal.

The mRNA sequence provided is 5′−UUUUGCCAUGUUUGUGCU−3′. To determine the sequence of the radiolabeled peptide produced by Renata, we can use the genetic code to translate the mRNA sequence into the corresponding amino acid sequence. Each codon in the mRNA sequence codes for a specific amino acid, and the sequence of codons determines the order of amino acids in the peptide chain. Using the genetic code, we can translate the mRNA sequence into the corresponding amino acids. Starting from the 5' end of the mRNA sequence, the codon UUU codes for the amino acid phenylalanine (Phe). The codon GCC codes for the amino acid alanine (Ala), and so on. By translating each codon, we can determine the sequence of amino acids in the peptide produced by Renata. Therefore, based on the provided mRNA sequence, the radiolabeled peptide sequence produced by Renata would be Phe-Ala-Met-Leu-Cys.

Answers

A major difference between fetal blood flow and adult blood flow is that in the fetus the internal iliac arteries are known as umbilical arteries. The inferior vena cava contains blood high in oxygen, and the pulmonary artery delivers blood to the lungs.The circulatory system is responsible for blood flow in the human body.

Blood circulation is divided into two distinct phases: fetal blood flow and adult blood flow. The fetus has a unique blood flow system. Oxygen and nutrients are provided to the fetus by the umbilical cord.The internal iliac arteries are the primary vessels that supply blood to the fetal pelvis and lower limbs. These arteries become known as the umbilical arteries in the fetus. The umbilical cord carries oxygenated blood from the placenta to the fetus and returns deoxygenated blood to the placenta.The inferior vena cava (IVC) is a major vein that carries deoxygenated blood from the lower half of the body to the right atrium of the heart in adults. Blood with high oxygen content is found in the IVC in the fetus.

The pulmonary artery carries deoxygenated blood from the heart to the lungs, whereas the pulmonary veins transport oxygenated blood from the lungs to the heart. Blood with low oxygen content is found in the femoral vein of the adult body.Fetal blood flow and adult blood flow differ significantly. The umbilical cord in the fetus carries oxygenated blood from the placenta to the fetus and returns deoxygenated blood to the placenta. The internal iliac arteries supply blood to the fetal pelvis and lower limbs. The inferior vena cava carries blood high in oxygen, while the pulmonary artery carries blood low in oxygen. The femoral vein carries blood low in oxygen in adult circulation.
