According to the International Union for Conservation of Nature (IUCN) giraffe numbers across the continent of Africa fell 40% between 1985 and 2015. The main threats to the giraffe population include a shrinking habit, conflict, and poaching. Checking the data, we see that while four subspecies have declining populations, four subspecies have growing populations. This is a modern-day example of natural selection at work. What elements of natural selection are at work here? A) Environmental conditions reduce the population numbers; only the fittest subspecies are able to survive. B) Overpopulation exists in a shrinking habitat; some subspecies decline in number; differential reproduction occurs. C) The death rate of some subspecies is elevated due to conflict and poaching; death is random; differential reproduction occurs. D) Genetic variation exists in the giraffe population across Africa; only those animals with a specific gene pool, represented by certain subspecies, can survive. Eliminate

Answers

Answer 1

Answer:

According to my calculations 1+1=2 so the answer is A

Explanation:

if 1+1=2 then the answer is A

Answer 2

Environmental conditions reduce population numbers; only the fittest subspecies are able to survive, which is an example of natural selection. Therefore, option A is correct.

What is natural selection?

According to Darwin's theory of evolution by natural selection, living creatures that have advantageous qualities tend to generate more children than those that don't. Over time, this causes changes in the characteristics of living things.

Only those individuals will survive that have favorable traits and adapts quickly according to the conditions.

Environmental conditions such as shrinking habits, conflict, and poaching cause a reduction in the giraffe population, only the fittest can survive. It is an example of natural selection. Therefore, option A is correct.

Which is NOT a function of the stem in plants?
O Store water
O Carry nutrients
O Provide support to the plant
O Anchor the plant in the ground

Answers

Answer:

yes D is the answer

Explanation:

cuz steam store water carry nutrients and of course provide support to the plant

Stems are the part of the plant and the structural axes that help in support and transport. The stem does not anchor plants to the ground.

What are stems?

Stems are the axis of the plant that bears shoots, leaves, buds, flowers, etc. The stem of the plant conducts water and mineral through the vascular system of the xylem and phloem.

The roots of the plant provide an anchor to the stem. They also store food and water in their structures that are used for further use and make them available at the time of requirement.

The stems are the mechanical structure that provides support to the plant parts and enables them to stand upright.

Therefore, option D. anchor to the ground is not provided by the stem.

All of the following are functions of asexual reproduction except producing gametes.

What do you mean asexual reproduction?

Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.

Asexual reproduction is a type of reproduction in which only one parent is involved. There are basically 5 types of asexual reproduction. These are binary fission, budding, vegetative reproduction, fragmentation and by spores.

The major disadvantages of asexual reproduction are: Lack of diversity- Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent.

What is a summary about how clouds form. Help asap plzzzz.

Answers

Clouds are formed when air contains as much water vapor as it can hold. This is called the saturation point, and it can be reached in two ways. First, moisture accumulates until it reaches the maximum amount the volume of air can hold. The other method reduces the temperature of the moisture filled air, which in turn lowers the amount of moisture it can contain. Saturation, therefore, is reached through evaporation and condensation, respectively. When saturation occurs, moisture becomes visible water droplets in the form of fog and clouds.

Genetic makeup of an organism is dependent upon the genes inherited from the parents. The genes when express are responsible for the development of specific traits in an organism. The environment is also responsible for contributing to the development of traits in an organism. For example, an organism is able to tolerate the cold environmental conditions and can survive in cold habitat as it has inherited traits from the parents but when exposed to hot environmental conditions then it will adapt to the changes in the environment due to development of heat tolerant trait. Also a person has inherited traits of short height from parents but when provided with nutritious food and performs regular physical activities the person had attained tallness due to environmental factors.

Which type of rock is shown in each of these photographs?

Answers

Let us see the choices

In the first image, a sedimentary rock is seen. Sand, mud, and gravel deposits build up over time to produce sedimentary rocks. Typically, these sediments are laid down in layers throughout time, and after being crushed and cemented together, they solidify into rocks.

Due to the variety of sediments that make up sedimentary rocks, these rocks frequently have a layered look. In the second image, an igneous rock is seen. When molten rock, or magma, cools and hardens, igneous rocks are created.

Numerous processes, such as the cooling of lava on the Earth's surface or the crystallisation of magma deep below the Earth's crust, can lead to the formation of these rocks.

Answers

Answer:

During replication, DNA unwinds into two distinct strands, with each strand producing a perfect duplicate of the other. A DNA strand is utilized during translation to create a corresponding strand of mRNA with uracil replacing thymine. Hence option A is correct.

What is replication of DNA?

Replication of DNA is defined as the biological process of splitting a single DNA molecule into two identical copies. A double-stranded DNA molecule is copied to create two identical DNA molecules during the DNA replication process. The three primary stages of replication are priming of the template strand, building of the new DNA segment, and opening of the double helix and separation of the DNA strands.

All biological cells contain it, and even though its synthesis takes place in the nucleus, it typically occurs in the cytoplasm of the cell. While DNA provides the instructions for the actions of the cell, RNA is in charge of translating those instructions into proteins that perform diverse cellular tasks.

Thus, during replication, DNA unwinds into two distinct strands, with each strand producing a perfect duplicate of the other. A DNA strand is utilized during translation to create a corresponding strand of mRNA with uracil replacing thymine. Hence option A is correct.
