The celiac ganglion ________. Group of answer choices is located near the base of the superior mesenteric artery arises from the greater splanchnic nerve projects postganglionic fibers that innervate the small intestine and the kidney and urinary bladder arises from the lesser splanchnic nerve arises from the lumbar splanchnic nerve

Answers

Answer:

The correct answer is ''arises from the greater splanchnic nerve''

Explanation:

The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.

Question
Use the text to identify the sentences with evidence that matches the claim.

Claim 1 --> Tropical rainforests contain more biodiversity than all other biomes.

1) Biodiversity refers to the total number of different species of all kinds living in an area.

2) Tropical rainforests have many of the climate characteristics that organisms of different species need to grow, such as warm temperatures, plenty of rain, and many food sources.

3) There are large amounts of daily sunlight, which provides a great deal of energy to a variety of rainforest organisms.

4) Surprisingly, rain forest soil is very poor.

5) Due to the large amounts of rainfall, nutrients are leached out of the soil quickly.

6) Warm temperatures cause dead organisms to decay quickly, and the nutrients are then used by many different plants.

Explanation:

A man is brachydactylous (very short fingers; rare autosomal dominant), and his wife is not. Both can taste the chemical phenylthiocarbamide (autosomal dominant; common allele), but their mothers could not. Give the genotypes of the couple. If the genes assort independently and the couple has four children, what is the probability of all of them being brachydactylous

Answers

Answer:

The correct answer is -

A) BbTt x bbTt

B) .5^4 or 1/16 or 0.0625

Explanation:

As it is given that Brachydactylus and PTC tasters both traits are autosomal dominant conditions which mean only one allele would be enough.

For Branchydactylus and For tasting :  man and women will be heterogeneous.

Hence,

The Genotype of man = BbTt

The Genotype of wife = bbTt

b. Answer = 0.0625

For Branchydactylus:

Bb X bb

Possible genotypes:

B b

b Bb( Brachydactylus) bb(normal)

b Bb (Brachydactylus) bb (normal)

The probability of a single child being Branchydactylus = 2/4 = 0.5

So,  Probability of all 4 child being Branchydactylus = .5 x .5 x .5 x .5 = 0.0625

Answers

Complete question:

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.

Group of answer choices

A) behavioral . . . prezygotic

B) mechanical . . . postzygotic

C) temporal . . . prezygotic

D) gametic . . . postzygotic

Answer:

A) behavioral . . . prezygotic

Explanation:

The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.

There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.

Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.

There are different types of reproductive barriers.

Pre-copulatory o pre-ziygotic:

Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.  

Postzygotic mechanisms or barriers include

Hybrid inviability,   Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.

Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.

The graph shows the supply and consumption of forests when the
consumption rate and population growth rate are both low.
When does consumption begin to surpass supply?

Answers

Answer:

In about 625years

Explanation:

According to the graphical representation depicted in this question, it shows the supply and consumption of forests when the consumption rate and population growth rate are both low. The green line represents the total consumption while the red line represents the total supply.

Based on observation of the graph, the total consumption exceeds or surpasses the total supply at a little above 600 years. Approximately, this can be said to be in about 625years.

Answer:

In about 625 years

Explanation:

Consumption has definitely surpassed supply by 700 years, but it only begins to surpass it around the 625 year mark according to the graph
