1 -

If the carrynig capacity of an area is 945, and it is carrying 1.100 individuals, what most likely will happen is that we'll see a decrease in the deers population, until it matches the carrying capacity. This will occur because there wont be enough resources available for all individuals.

Answer:

E.

2 -

The biotic and abiotic limitations are what determine the carrying capacity of a population. Which in other words is simply the amount of living and non-living things that can occupy an area.

If you get a wagon, and say the carrying capacity of that wagon is 100 people, you'll be counting the number of seats (number of people that can sit), the number of people that can stand plus non-living factors such as the space occupied by the seats, metal bars, etc.

Answer:

C.

Image 1-

Exploitation - you usually here this term being used with minerals in stuff, but it can also occur with animals through excessive hunting and poaching.

Invasive species - these are species that are introduced into an ecosystem they do not belong to, and therefore, most of the time cause a lot of damage and some of this damage can be irreveersible, like the extinction of species.

Answers:

B and C.

Image 2 -

There is not much to think about it this image. The regions with a very high threat posed by the invasive species are the ones that will suffer the most.

Answer:

North-American square.

Image 3-

Insects do not go out in windy or rainy days, also because these tend to be cold days.

Answer:

First week - Wednesday.

Second week - Monday, Friday and Saturday.

Hope it helped,

Explanation:

Among the physical factors are the elements corresponding to the climate, such as temperature, rainfall, soil composition and water composition, altitude, latitude, etc., these factors are known as abiotic factors. Without these factors, there would be no life. If these factors are optimal for a living being, it develops fully. However, if the opposite happens, harmful effects appear in your life.

The United States ranks 50th in the world for maternal mortality and 41st among industrialized nations for infant mortality rate
siniylev [52]

Answer:

Answer is B. Ensuring early and adequate prenatal care.

Explanation:

Prenatal care can be described as the care, such as information and medical care , given to pregnant women during pregnancy , before delivery.

This is very important , because it prevents complications during pregnancy, which can lead to maternal mortality, and support the birth of healthy children.

Infant mortality is the death of the child at birth or shortly after, while maternal mortality is the death of pregnant women during pregnancy or shortly after delivery.

Therefore, ensuring early and adequate prenatal care is the best factor that must be put in place to address the issue of maternal mortality and infant mortality rate.

Explain the properties of RNA
masya89 [10]

Answer:

RNA forms in the nucleolus, and then moves to specialized regions of the cytoplasm depending on the type of RNA formed.

RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions. RNA’s larger helical grooves mean it is more easily subject to attack by enzymes.

RNA strands are continually made, broken down and reused.

RNA is more resistant to damage from UV light than DNA.

RNA’s mutation rate is relatively higher.

Unusual bases may be present.

The number of RNA may differ from cell to cell.

Rate of renaturation after melting is quick.

RNA is more versatile than DNA, capable of performing numerous, diverse tasks in an organism.

RNA or ribonucleic acid is a polymer of nucleotides which is made up of a ribose sugar, a phosphate, and bases such as adenine, guanine, cytosine, and uracil.

It is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes.
