How are<br> mosquitos infected with Wolbachia?
bazaltina [42]

Answer:Wolbachia can only be transmitted from parent to offspring inside the female's egg. When a male mosquito that carries Wolbachia mates with a female without the bacteria then that female's eggs don't hatch. Wolbachia-infected female mosquitoes, however, produce normal numbers of offspring – which carry Wolbachia.

A boxer is competing in a match. Which describes the roles of endocrine and neural controls as he boxes?
andrew-mc [135]

Answer:

The correct answer is "The nervous system transmits pain, while the endocrine system elicits the fight or flight response".

Explanation:

One of the roles of the nervous system is to transmit pain to alarm the body that something is going on and that it acts accordingly. The nerve pathway is the one that carries the message of pain from the affected area to the spinal cord and up to the brain. On the other hand, the endocrine system is the one that elicits the fight or flight response. During stressful conditions, the adrenal glands of the endocrine system release epinephrine and norepinephrine that acts during the fight or flight response.

The table below summarizes Mendel’s results for the F2 generation. Mendel’s Results Plant height 787 tall 277 short Flower color
Gnom [1K]

Answer:

2001

Explanation:

This question showcases a table that displays Mendel's results (figures) when he crossed pea plants and observed different characters in the plant. Mendel worked with different phenotypic characteristics in the pea plant.

According to the table, the result were for seven characteristics including height, flower color, flower position, pod color, pod shape, seed color, seed shape. Based on the observation of the number of F2 offsprings that possessed dominant trait and recessive trait for each character, we will notice that it follows an approximate phenotypic ratio of 3:1

1. Plant height 787 tall 277 short (3:1)

2. Flower color 705 purple 224 white (3:1)

3. Flower position 651 middle of stem 207 end of stem (3:1)

4. Pod color 428 green 152 yellow (3:1)

5. Pod shape 882 inflated 299 constricted (3:1)

6. Seed color 6,022 yellow X green

7. Seed shape 5,474 smooth 1,850 wrinkled (3:1)

This 3 dominant : 1 recessive ratio is the ratio got in the F2 offsprings when he observed the seven characteristics in pea plants. Hence, the seed color will also follow the same 3:1 ratio

Therefore, 2001 is the result Mendel obtained in the F2 offsprings for the recessive trait of seed color characteristics in his experiment, which actually depicts the 3:1 ratio. Hence, X (green seed color) is 2001

A pea plant with purple flowers (and unknown genotype) is crossed with a pea plant with white flowers. one-half of the offspring
Archy [21]
The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).  
 For example:  
 If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>
