Drag each tile to the correct location on the chart. What are the pros and cons of sexual and asexual reproduction?
levacccp [35]

Answer:

Sexual reproduction:

Pros: leads to greater genetic variation.

Cons: requires more time and energy.

Asexual reproduction:

Pros: Does not require finding a mate.

Cons: Produce less genetic variation.

Explanation:

Sexual reproduction is a type of reproduction in higher organisms, in which new individuals are formed by combining genetic information from two different types (sexes) of individuals.

Advantage: Sexual reproduction leads to higher genetic variation due to recombination between genetic material of female and male gamete during meiosis.

Disadvantage: Sexual reproduction is a time and energy consuming process as it needs interaction between mates and organisms which are produced sexually require more time for development.

Asexual reproduction involves formation of new organisms from a single parent organism without gamete fusion.

Advantage: Asexual reproduction requires less time and energy as it does not require finding a mate.

Disadvantage: Asexual reproduction produces less genetic variations as it involves only parent organisms (no mixing of genetic information) and the only source of variations are random mutations.

What occurs if a t cell binds to an antigen and the t cell does not receive a co-stimulatory signal?
tresset_1 [31]
The correct answer is that "the T cell enters a state of anergy".

The activation of T cells requires two signals: (1) antigen specific signal presented by an antigen presenting cell (either a macrophage or a dendritic cell) that activates t cell receptors and (2) co-stimulatory signals that is not antigen specific but rather found in the plasma membrane of the antigen presenting cell (i.e. CD28). In the absence of a co-stimulatory signal, the t cell will enter a state of anergy or the inability to produce an immune response toward an offending antigen.
