The hormone which aids in the growth of gonads is Gonadotropin. The correct option is gonadotropin.
Gonadotropins are defined as the hormones which play an important role in the growth and development of gonads. The gonads refer to the male and female reproductive organs, such as the testes and ovaries. Gonadotropins stimulate the production of sex hormones and even regulate the reproductive processes. These hom*onesare essential for the normal functioning of the reproductive system.
Gonadotropins are classified as glycoprotein hormones which are secreted by gonadotropic cells of the anterior pituitary which is present in vertebrates.This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG),as well as at least two forms of fish gonadotropins.
Thus, the correct option is gonadotropin.

During which step of the water cycle does water combine with pollutants on
Earth's surface?
Precipitation
Transpiration
Evaporation
Runoff
Water is taken in
by animals
Plants take up water
from the ground
Percolation
A. Transpiration
B. Percolation
C. Runoff
D. Precipitation
Answers
C because the water is flowing from the mountains so trash can come down with it
Runoff is a step in the water cycle where the water combines with pollutants on Earth's surface. Therefore, the correct statement is option D.
Plants take up water from the ground through transpiration process. Therefore, the correct statement is option A.
What is runoff water cycle?
During the water cycle, when water combines with the pollutants present on the surface of the earth, the process is called runoff. During runoff, water comes from the melting snow or other resources and moves towards the surface of the land, thereby, carrying pollutants and other chemicals along with it from urban or agricultural areas and ultimately carried the pollutants into streams and rivers, and eventually into lakes and oceans.
Therefore, runoff water causes various harmful effects on human health as well as aquatic life. Therefore, runoff water should be properly treated to prevent pollution.
Plants take up water from the ground through a process called transpiration where water present in the soil gets absorbed by the roots of the plants and then further transported to the top of the plant through the stem and also into the leaves.
Therefore, runoff is a step in the water cycle where the water combines with pollutants on Earth's surface and plants take up water from the ground through transpiration process.

Most scientists agree that saturated fats contribute to high levels of “bad” cholesterol, while monounsaturated fats and polyunsaturated fats lower this type of cholesterol. The table below shows data about fats in some common foods.
Food (14 g)Saturated fat (g)Monounsaturated fat (g)Polyunsaturated fat (g)
Canola oil1.0 8.9 3.9
Margarine1.6 5.4 3.4
Olive oil 1.9 9.9 1.4
Lard 5.0 5.8 1.4
Butter 7.9 3.7 0.5
Joyce and Linda are identical twins who are 50 years old and enjoy exercising daily. Joyce avoids eating any dairy or animal products and eats granola made with canola oil for breakfast. Linda prefers rich foods, and eats bacon, eggs, and buttered toast each morning. Which statement describes a logical inference that can be made from the provided information?
a)Butter has higher levels of saturated fats in it than canola oil.
b)Linda and Joyce both have high levels of “bad” cholesterol.
c)Butter contains a small amount of polyunsaturated fats.
d)Linda has a higher level of “bad” cholesterol than Joyce.
Answers
Answer: D: Linda has a higher level of "bad" Cholesterol than Joyce
Explanation: From the first sentence Saturated fat contributes to high level of bad cholesterol. Buttered food, bacon ( Lard) are significantly high in saturated fat which contributes to high level of bad cholesterol and that's what Linda is eating. Joyce on the other hand avoids animal products and feeds on granola from Canola oil which is low in saturated fat.
The logical conclusion base on this diet is Joyce has low level of bad cholesterol while Linda has high level of bad cholesterol
