Scientific Theory change but not thrown away because scientist continue looking for possibilities and exact proportion to prove such theory, though it is change because they always conducted hypnosis in every theory and once it proves something different they conduct another hypothesis for more actual evidence.

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 [ ].

Which three steps describe how an animal obtains and uses energy for growth?
harina [27]

Answer:

Option C. First, an animal eats another organism. Then, food is broken down into smaller molecules. Next, the animal's cells use molecules to make new cells.

Explanation:

When one animal eats another animal, the body of organisms is made of higher molecules such as carbohydrate, protein and lipids. These large molecules are broken down into simpler substances in the stomach such as glucose, amino acid and faty acid. These substances are absorbed by the body and release energy from them.

The DNA sense strand for a particular amino acid is 5′-ATG-3′. What RNA sequence would be transcribed for this codon, what tRNA
irina1246 [14]

Answer:

RNA sequence- 5' AUG 3',

tRNA anticodon- 3' UAC 5'

Amino acid- methionine

Explanation:

DNA contains two strands of sense and antisense. The mRNA sequence is produced by the antisense strand of DNA. So if the DNA sense strand has ATG sequence then according to the complementary base pairing the sequence against it would be 3' TAC 5'.

In RNA in place of thymine, Uracil comes so here according to complementary base pairing rule the sequence of codon in RNA would be 5' AUG 3'. As tRNA contains anticodon sequence which is complementary to mRNA codon sequence therefore the anticodon sequence would be 3' UAC 5'.

Every triplet codon in mRNA codes for a particular amino acid and AUG codon is called start codon which codes for methionine. So methionine would be added against AUG codon.
