Replicate the following (write the complementary DNA strand); ATT ACG CGC

2 answers:

7 0

Sorry but… the complementary base pairs are actually:
adenine and thymine
cytosine and guanine

So every A will be matched with a T and every C with a G.

This means your replicated sequence should be:

TAA TGC GCG

GCC GTA TAT

Adenine pairs with guanine.

Cytosine pairs with thymine.

Hope it helps!

Inserting NGT can gain access to the stomach and its content. Draining of stomach content is possible, decompression or obtain a specimen of the gastric content is possible. This can allow gastric immobility and gastric obstruction to be identified. This is usually contraindicted to patients with facial trauma due to possibility of inserting the tube intracranially. Complications that can be expected are aspiration, trauma.

In contrast with the ______________, the soil of the ______________ is more nutrient-rich and this type of biome has fewer insec

aleksley [76]

Answer;

-Tropical rainforest; tropical seasonal forest

In contrast with the tropical rainforest, the soil of the tropical seasonal forest is more nutrient-rich and this type of biome has fewer insects, parasites, and fungal diseases. therefore, in many places, these areas are highly endangered.

Explanation;

The tropical rainforest is one of the world's most threatened biomes, despite being home to some of the most diverse and unique species on the planet. The tropical rainforest is a biome with a constant temperature and a high rainfall. The level of humidity and density of the vegetation give the ecosystem a unique water and nutrient cycle. Rainforests around the world are threatened by human expansion.

The tropical seasonal forest has more or less densely growing trees which lose their leaves during the dry season. It typically contain a range of tree species: only some of which drop some or all of their leaves during the dry season.

Please help me - fill in the blank

Lorico [155]

In this question, we will understand the air path from entering the nasal passages to reaching the alveoli, where gas exchange takes place.

<h3>What is the air's path to the lungs?</h3>

The air penetrates through the nasal passages, passes through the pharynx, larynx and trachea, bronchi, reaching the lungs where it travels through the bronchioles until reaching the alveoli, where gas exchange takes place. The difference between inspired and expired air is in the concentration of oxygen and carbon dioxide.

a) Blood leaving the air sacs is rich in oxygen gas.

b) When exhaling, the breath is rich in carbon dioxide.

c) If you trace the path of air moving through the respiratory system, it would enter through the mouth and nose. It continues through the pharynx, into the larynx, through the tubes and into the trachea and finally reaches the lungs.

Identify two specific populations that most likely increased in number after the mountain lion population decreased. Explain why

bezimeni [28]

Any change that occurs at any link of a trophic web will affect the other links. The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.

----------------------------

The trophic web is a relationship process between different organisms, through which occurs transference of energy. The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.

The first link corresponds to a producer organism -autotroph-.

The following links are the consumers -heterotrophs-: herbivores and carnivores.

The last links are the decomposers that degrade organic matter from dead organisms.

As it is a web, all organisms are equilibrated until a change occurs.

When the change affects any of the involved links, there can be a cascade effect on the web.

A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.

According to the provided trophic web, puma feeds on deer and rabbit.

Since puma was killed, their population size sharply decreased.

This fact followed the predator-prey cycle, in which the predator regulates the prey population size and vice-versa. When there is a decrease in the predator population size, the prey population increases in size because of the absence of their natural predators.

In the absence of puma, deer and rabbits increase their population size. They live in an environment with no predators and enough resources.

The number of individuals of each species increased, and the amount of food consumed increased too.

This change negatively affected grasses and grains, which were over-consumed. Also, crickets and mice were affected too because they compete for the same food source.

So, cascade effects would be as follows,

1) The decreased in the puma population size caused an increase in the deer and rabbit population size.

2) The increase in the deer and rabbit population size caused a decrease in the grains and grasses species population, because they were over consumed.

3) The decrease in grains and grasses caused a decrease in the cricket and mouse population, because they feed on the first ones, competing with deer and rabbits for food.

The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.
