An Inflammatory response typically includes: Group of answer choices increased activity of phagocytes in an inflamed area inhibiting the release of white blood cells from bone marrow release of substances to decrease the blood supply to an inflamed area reduced permeability of blood vessels to conserve plasma
Answers
Answer:
increased activity of phagocytes in an inflamed area
Explanation:
An inflammatory response is the way the body defends itself against attacks by microbes, physical or chemical agents. In other words, this is how organisms defend and inhibit damage from attacks. The inflammatory response allows high phagocyte activities in the inflamed area. Phagocytes are immunity-related cells that attack foreign and invasive substances, bacteria and dead cells.

Part of a process necessary for reproduction in complex organisms is explained below, and the correct options are gametes that could be involved in the formation of a zygote, which is in option D.
What is a zygote?Reproduction in complex organisms involves a process called sexual reproduction, which involves the fusion of gametes from two parents, such as the male making the sperm and the female making the ovum, and then the zygote is formed. In the case of humans, this zygote develops into a baby after 9 months.
Hence, the correct options are gametes that could be involved in the formation of a zygote, which is in option D.

Culture includes a society's knowledge, customs, and achievements. O D. Cultures are groups of people united by blood relationships. SUBMIT
Answers
Answer:
B. Every human has a unique set of cultural traits and practices.
Explanation:
Culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
This ultimately implies that, culture are acquired and passed from one generation to another.
A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication.
This ultimately implies that, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.
Hence, the statement which is true of human cultures is that every human (race) has a unique set of cultural traits and practices that were acquired from the environment and society.

Answer:
blastopore
Explanation:
Involution is the second stage after invagination during frog gastrulation. Involution occurs at the blastopore when the marginal zone cells get to the tip of the blastopore, make an inward turn and then move along the inner exterior of the outer cells sheets.
This means that the cells found at the lip of the blastopore and always undergoing change and the first of these cells to develop into the dorsal lip are the endodermal cells. Next are the mesoderm cells that form the Notochord.

What is the mechanism by which binding of testosterone to the testosterone receptor leads to upregulated gene transcription
Answers
Answer:
This binding causes a conformational change in the receptor which enters into the nucleus and binds DNA to activate transcription
Explanation:
Testosterone is a steroid hormone responsible for inducing protein synthesis and growth of tissues with androgen receptors. Testosterone receptors, also known as androgen receptors, are a class of nuclear receptors activated by binding androgenic hormones (e.g. testosterone) in the cytoplasm, whose binding induces a conformational change of the receptors that are subsequently translocated to the nucleus. Within the cell nucleus, these activated receptors form homodimers that bind DNA in order to promote the transcription of target genes capable of regulating cell growth, cell cycle progression and survival.
Rheumatoid arthritis is commonly associated with the presence of rheumatoid factor autoantibodies in the bloodstream. This indicates that rheumatoid arthritis is likely to be a. an infective process. b. caused by bacterial infection. c. an autoimmune process. d. because of an enzymatic defect.
Answers
Answer:
The correct answer is - c. an autoimmune process
Explanation:
Rheumatoid arthritis is a disease or condition that affects the joints mainly by swollen, and painful joints. It is an autoimmune disease as the person's own immune system attacks the body.
The presence of rheumatoid factor autoantibodies states that it is an autoimmune process. There are other autoantibodies also associated with this type of arthritis that are rheumatoid factors (RF), anti‐keratin antibodies (AKA), anti‐filaggrin antibodies (AFA), and anti‐perinuclear factor (APF).

The factor that may contribute to a population maintaining Hardy-Weinberg equilibrium is there are no mutations in the DNA of the population. So, the correct option is A.
What do you mean by Mutation?The sudden, stable, and inheritable changes in the genetic material of an organism, are called mutations.
There are some assumptions of Hardy-Weinberg equilibrium. They are.
The population is large.The members of the population mate randomly with each other.No migration occurs between populations.No new mutations are favorable. No survival or reproductive advantage.Therefore, the factor that may contribute to a population maintaining Hardy-Weinberg equilibrium is there are no mutations in the DNA of the population.

Answers
Answer:
The correct answer is - alternate versions of a gene.
Explanation:
In a cell, if there are two copies of each chromosome, these are called homologous chromosomes, one come from the father and the other comes from the mother, which helps in promoting the variety and stability of a species.
Different or alternate versions of genes are possible that can result in two phenotypes for the same trait, these alternate versions called alleles. Alleles can be dominant and recessive.
Fire and Mello conducted an experiment where they added no gene X RNA (b), anti-sense gene X RNA (c) or double stranded gene X RNA (d) to C. elegans embryos. They then did a hybridization experiment examining gene X mRNA levels in the embryo. Square (a) is a no probe control. How does this act as a control
Answers
Answer:
The correct answer is - It shows that an RNA probe is necessary to get a signal.
Explanation:
A probe is a specific single-stranded sequence of DNA or RNA that recognizes its complementary sequence in a particular sample genome for synthesis. The RNA probe is placed into close contact with the given sample under a specific environment that allows the RNA probe sequence to hybridize with its complementary sequence.
In this case, square a is the condition where no RNA probe is persent whereas all three other conditions have some sort of RNA probe, however, in C there is no Gene X probe but their probe present. To get a signal in hybridization RNA probe is required and that can be used as control as it can be used to compare if a signal is received or not.
