Biology
1 answer:
jarptica [38.1K]3 years ago
5 0

Answer:

The acquired immune system, with help from the innate system, produces cells (antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child's body.

2) How many solutions does the equation 4x + 2(x-5) = 3(2x - 4) have? Write down the final form as well as if it has no solution
Brilliant_brown [7]

Answer:

0 = -2, hence no solution.

Explanation:

4x + 2(x-5) = 3(2x-4)

4x + 2x - 10 = 6x - 12

     6x - 6x = -12 + 10

               0 = -2

explain how having a haploid number of chromosomes contributes to the function of gametes in a life cycle
kotegsom [21]
Having the haploid number of chromosomes allows the zygote to have the correct number. If gametes weren't haploid, every generation of organisms would have twice as many chromosomes as their parents. I hope my answer has come to your help. God bless and have a nice day ahead!

More than half a century ago, two cell biologists published details of their research involving isolated membrane vesicles from
fiasKO [112]

Answer:

Plasma membrane is the semi-permeable membrane that allow the movement of some selected particles only against the concentration gradient or along the concentration gradient.

Different substances can be move through the diffusion, active process and passive process. The hydrogen in the vesicle has been moved through the facilitated diffusion.  In this process, the hydrogen ions will move along the concentration gradient without the requirement of energy but requires the channel protein for its transport.

Mendel crossed peas having round seeds and yellow cotyledons (seed leaves) with peas having wrinkled seeds and green cotyledons.
Kruka [31]

Answer:

Let:

Y = Yellow           R = Round

y = green             r = Wrinkled

If you look at the F1 generation, all the plants are round and yellow, so these are the dominant traits and each offspring is heterozygous for both traits. The cross for the F2 generation would then be:

<em>YyRr x YyRr</em>

In a Punnett it would look like the attached picture.

For the forked-line diagram, first you will need to know the gentypes and ratio of each trait in a monohybrid cross. Select one trait, and then branch each gentype to the next trait, linking it with each possible genotype combination of the monohybrid cross.

Attached is a picture of the Forked Branch diagram for this cross.
