Answer:
This question lacks options, options are:
A) histamine
B) gastrin
C) secretin
D) ACh
The correct answer is C.
Hormones or paracrines that inhibit gastric secretion include <u>secretin
</u>.
Explanation:
Hormones pass into the blood that waters the digestive system, go to the heart, circulate through the arteries and return to the digestive system, where they stimulate the production of digestive juices. The hormones that control digestion are gastrin, secretin and cholecystokinin. Secretin is stimulated by intestinal acid at the duodenal level. Its effect inhibits gastric acid secretion, prostaglandin secretion and via somatostatin release. It decreases gastric emptying and stimulates bile and pancreatic bicarbonate secretion.

Answer:
Both parents have white fur. <em>The only</em> way that this can happen is if their genotypes are both <em>homozygous (bb)</em>. Therefore, both parents pass the (b) allele to every offspring. When you combine two of these alleles, the resulting genotype is <em>(bb);</em> therefore, the resulting offspring have white fur.
Explanation:
A homozygous trait can be described as a trait in which both the alleles for a gene are similar. A heterozygous trait can be described as a trait in which both the alleles of a gene are different. If an allele masks the effect of another allele, it is said to be dominant. the allele that gets suppressed is termed as recessive.
Hence, for a recessive trait to occur both the alleles of a gene should be homozygous recessive.

4.6 million years ago the earth had less green house gasses so the atmosphere was cooler rather than hotter.
Answer:
a. establishment of left-right asymmetry
Explanation:
- Cardiac looping is the process in which the heart transforms itself from a straight embryonic heart into a loop that is wounded helically.
- The looping of the heart takes place on the 23rd day of development.
- As a result of this looping, there is bending of the cranial portion of the heart to the towards the right end and the caudal portion of the heart towards the left end.
- At the end of this looping the atrium takes up a dorsal and cranial position and the ventricle is displaced towards left.
- Thus, the outcome of looping is the establishment of left-right asymmetry.
