Give two specific examples where asexual reproduction happens in nature.

1 answer:

5 0

Answer: Bacteria produce asexually, making copies of itself to spread. Plants also produce asexually, this happens in several ways one way s binary fission. This is asexual reproduction by a separation of the body into two new bodies. Simply copies of the original.

Describe these structures found within the kidneys

garik1379 [7]

The structures are nephrons which gets blood through the [renal artery]. The nephrons also consist of the [afférent and efferent artérioles], the latter of which is much narrower causing a high pressure to exist in the [glomerulus] (blood vessels in that ball structure) so that ultrafiltration can occur and the ultrafiltrate is passed into the [Bowman’s capsule]. The Bowman’s capsule consists of podocytes which are cells that form a microscopic pore so that small molecules can pass through (ions and such). There is the [proximal convoluted tube] that makes the contents flow downwards (and allows water to exit so the water potential inside is low) and the [distal convoluted tube] that makes the contents go upwards (and allows water to re-enter which increases the water potential inside). These are both partially permeable and set up a concentration gradient for the reabsorption of water from the urine. These tubes lead into the [collecting duct] which further reabsorb the water.

All the structures of the kidney are in [ ].

Answer:

<h2>616 Short with white flower </h2><h2>1850 Tall with white flower </h2><h2>1850 Short with purple flower</h2>

Explanation:

A dihybrid cross is in which two genes of two different traits are crossed

As given, two dihybrid pea plants (tall with purple flower) are mated, resulting 5550 out of 9866 were tall with purple.

T= tall

t= short,

P= purple,

p= white;

So genotype of parents are TtPp ; T is dominant over t, P is dominant over p.

Crossing between two parens= TtPp × TtPp

so gamets are = parent 1: TP, Tp, tP, tp and parent 2: TP, Tp, tP, tp

Hence the four different gametes formed.

Now arrange the gametes on the top and left side of a Punnett square it'll genotypically results into different combinations, by which phenotypic ratios can be calculated.

offspring are = TTPP, TTPp, TtPP, TtPp....................TTpp, Ttpp.....ttPP, ttPp.......ttpp

(T_P_)= Tall with purple flower,

(T_pp)= tall with white flower,

(ttP_)= short with purple flower,

(ttpp)= short with white flower.

so it show 12:3:3:1 ratio'

Phenotypic classes are:

616 Short with white flower

1850 Tall with white flower

1850 Short with purple flower

GaryK [48]

Answer:

When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss. Slate is another common metamorphic rock that forms from shale. Limestone, a sedimentary rock, will change into the metamorphic rock marble if the right conditions are met.

What is dna fingerprint for

harkovskaia [24]

Answer:

DNA fingerprinting is a method used to identify living things based on samples of their DNA. Instead of looking at the whole sequence of a person’s DNA, these techniques look at the presence or absence of common markers that can be quickly and easily identified. DNA Fingerprinting Explained
