Help please will give brainliest to anyone who is good at ​

Biology
1 answer:
SpyIntel [72]3 years ago
4 0

Answer:

The way to figure this this type of question out is card by card. So the first card in the second hand is 2 in 52 (It can match either of the cards in the previous hand). × 1 in 51 ( it has to match the card that was not matched by the first card and there are 51 choises left). So 2 in 52 = 1 in 26 x 1 in 51 = 1 in 26 x 51 = 1 in 1326

Identify the process that is necessary for sexual reproduction. Also, explain why it is necessary and identify how this process
Olenka [21]

Answer:

The correct answer would be meiosis.

In diploid organisms, meiosis is the process that results in the formation of four haploid daughter cells from single diploid parent cell. Each of the daughter cell contains half the number of chromosomes present in parent cell.

It results in the formation of haploid gametes (sperm in males and eggs in females) which is essential in the process of sexual reproduction.

The fusion of gametes results in the formation of diploid zygote that is, maintains the diploid nature of the organism.

Hence, in absence of meiotic division the chromosomal number would keep on doubling after each generation.

In addition, crossing over (exchange of genetic material between non-sister chromatids) also takes in the prophase-I of meiosis I. It increases the genetic variation within organisms of the species. It may add survival adaptations to the population.

When culturing a chemoorganoheterophic bacterium, what outcome is LEAST likely to occur if ammonia and phosphate are provided at
inna [77]

Options:

A) Cells require much less P to grow than N, so extra P will be used for ATP synthesis and result in a faster growth rate.

B) Cells will never consume all of the phosphate, because N is needed in higher quantities than P.

C) The final biomass of cells will be no different than if only 50% of the phosphate was provided.

D) The bacteria will import all of the ammonia to use for biosynthetic pathways.

Answer:A) Cells require much less P to grow than N, so extra P will be used for ATP synthesis and result in a faster growth rate.

Explanation: Chemoorganoheterophic Bacteria are bacteria which requires the supply of organic nutrients of Carbon and metabolic energy. If Ammonia and potassium are provided at equal amount or concentration, the least likely occurrence will be that

Cells require much less P(potassium) to grow than N(Nitrogen), so extra P(potassium) will be used for ATP synthesis and result in a faster growth rate. This is so because Chemoorganoheterophic Bacteria requires organic supply of nutrients in the form of Carbon and metabolic energy.

How are gametes different from all of the other cells that make up an organism
12345 [234]

Answer:

How are gametes different from all of the other cells that make up an organism.

Reasons are not far fetched as result of fertilization occurrence after mating which leads to having multiple cells in a gamete. The fusion of male and female organism leads to formation of gametes which consists of multiple cells
