Answer:
To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.

Not all traits are determined solely by genes. Many traits have been found to exhibit phenotypic plasticity, which
occurs when individuals with the same genotype exhibit different phenotypes in different environments. Which of the
following is an exampleof phenotypic plasticity?
Well-maintained hedges can be shaped into artistic displays.
O A person who experienced malnutrition as a child is short in stature as an adult.
O Bears living in the arctic developed white fur and cold tolerance over many generations.
Certain breeds of dog have been bred for specific traits, such as poodles being bred for intelligence.
Answer:
O A person who experienced malnutrition as a child is short in stature as an adult.
Explanation:
Height is a quantitative trait, i.e., a phenotypic trait that depends on the combined action of many genes and the environment. Moreover, phenotypic plasticity can be defined as the ability of one genotype to produce different phenotypes in different environments. In consequence, quantitative traits are influenced by environmental factors and exhibit phenotypic plasticity. Quantitative traits are characterized to have a large variety of phenotypes and follow a normal distribution (a bell-shaped curve) when they are drawn.

Explain what would happen to the number of rats if the eagles died from a disease.
Answer:
If eagles died of disease, the number of snakes that prey on rats will increase, which will decrease the number of rats. Also, eagles will cause the and rabbit population to increase, decreasing the plant population and therefore decreasing the rat population because of the lack of food.
tldr; rats will decrease if eagles died of disease.
Answer:
The rabbit population willl increase because the eagles are not present to feaast on them. The population of the snake will also increase since the Eagles are not present and the rat's population will increase as welll because it's only 1 animal who is eating them.

What effect does aerosol pollution have on climate?
A. Permafrost thawing
B. Atmospheric cooling
C. Sea level rising
Answer:
Aerosols can influence the Earth's climate in two ways. When the sky is clear (devoid of clouds), aerosols can reflect incoming sunlight back to outer space – the direct effect. This blocks part of the energy that would have reached the surface, thus having a cool effect on the climate.
Explanation:
Aerosol pollution has an atmospheric cooling effect on the climate. Therefore option B is correct.
Aerosol pollution, which refers to the presence of fine particles suspended in the air, can have a significant impact on the climate.
Aerosols, such as sulfate particles from industrial emissions or volcanic ash, can scatter and absorb sunlight in the atmosphere. This leads to a phenomenon known as atmospheric cooling.
Aerosols reflect solar radiation back into space, reducing the amount of sunlight reaching the Earth's surface. This cooling effect counteracts the warming caused by greenhouse gases, such as carbon dioxide.
Therefore option B Atmospheric cooling is correct.

Answer:
bases.
Explanation:
Nucleotides are the basic building blocks that make up DNA, consisting of a deoxyribose sugar, phosphate group, and nitrogenous base. The main difference between the four nucleotides is the nitrogenous base, Adenine, Thymine, Guanine, or Cytosine. Adenine pairs with Thymine, and Guanine pairs with Cytosine. The order in which these pairs come in code for proteins and hold genetic information.

Which of the following is a problem faced by the global economy? A. Decreasing cost of renewable resources O B. Increasing greenhouse gas emissions C. Increasing environmental awareness D. Decreasing human population
Answer:
B. Increasing greenhouse gas emissions
Explanation:
Increasing greenhouse gas emission leads to the global warming which is not only harmful for environment but also harmful for global economy.
Increasing emission of greenhouse gases rises the CO2 levels in the atmosphere which lowers the nutritional value of crops and highly affects the agricultural economy of the globally.
Greenhouse gases increases demand of space cooling which eventually decrease the demand for space heating, which is very costly.
Increasing emission of greenhouse gases has direct impact on climate change and climate change has indirect impact on several sectors which affect economy globally such as mining, manufacturing, trade, and finance.
Hence, the correct answer is "B. Increasing greenhouse gas emissions".
Describe how the egg gets from the ovary to the site of fertilisation.
Answer:
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.
