Memory cells do not require b cell receptors. This statement is False.

Memory B cells may recognize an antigen and produce a particular antibody response because they have B cell receptors (BCRs) on their cell membrane that are identical to those on their parent cells.
A B-lymphocyte subtype known as a memory B cell (MBC) is a component of the adaptive immune system. Within the germinal centers of the secondary lymphoid organs, these cells grow.
Memory B cells can remain dormant in the blood stream for years at a time.
Their purpose is to memorize the properties of the antigen that initially activated their parent B cell, so that when the memory B cell comes into contact with that antigen in the future.
It will cause an expedited and potent secondary immune response. B cell receptors are found on memory B cells (BCRs)

KatRina [158]

A "ring of Life" is more appropriate to describe the relationship between archaea, bacteria, and eukaryotes than a “tree of life “, because each group of single-celled prokaryotic organisms produces something that is a necessity to another group of single-celled prokaryotic organisms. so therefor it is not like a tree of life which is more of a hierarchy than an everyone, and everything is equal Ring of Life.

Stem color of tomato plants is known to be under the genetic control of at least one pair of alleles such that A- results in the

fredd [130]

Answer:

Genotype - AaMm

Phenotype - Heterozygous purple stem and fruit with two locules

Explanation:

Given

Trait 1 - Recessive allele for green color stem is represented by a

and dominant allele for purple color stem is represented by A

Trait 2 - Production of two locules in the tomato fruit is a dominant trait and is represented by "M" and production of multiple locules in the tomato fruit is a recessive trait and is represented by "m"

F1 cross is carried between tomato plant with purple stem and fruit with two locules (AAMM) and a tomato plant that have fruit with multiple locules and a green stem (aamm)

The following offspring will be produced

AM AM AM AM

am AaMm AaMm AaMm AaMm

Genotype - AaMm

Phenotype - Heterozygous purple stem and fruit with two locules
