A student made a model of an onion skin cell she viewed using a microscope. The scale is 1:500.The students cell model has a length of 15cm. How many centimeters is the real cells length?
Answer:
Length of the real cells = 7500 cm
Explanation:
A scale model is a physical representation of an object that has the same aspects as that of the object.
A scale model can be used in fields like engineering, film making, salesmanship, etc
Length of the student's cell model = 15 cm
The scale is [tex]1:500[/tex]
So,
Length of the student's cell model / Length of the real cells = [tex]1:500[/tex]
15 / Length of the real cells = [tex]1:500[/tex]
Length of the real cells = 15 × 500 = 7500 cm
Answer:
7500 cm

Which climatic zone is always hot and humid? arid, tropical wet, temperate continental, Mediterranean
Answer:tropical wet, is the anwers
Explanation:
The tropical wet climate zone is the climate zone that is consistently hot and humid. This climate zone is characterized by year-round high temperatures and high humidity, with average temperatures of 80°F (27°C) or more, and annual precipitation of 59 inches (1,500 mm) or more.
What is tropical wet climate zone?The tropical wet climate zone is a type of climate that can be found in areas close to the equator. It is distinguished by high temperature, year-round high humidity and abundant rainfall. Equatorial climate or tropical rainforest climate are other names for this climate zone.
One of the most ecologically diverse regions on Earth is the tropical wet climate zone, which is also an important supplier of natural resources such as timber, fruits and medicinal plants. Deforestation, climate change, and other human activities also pose threats to the region, and they have the potential to have major impacts on the natural and economic systems that depend on this climate zone.
Therefore, the tropical wet climate zone is the climate zone that is consistently hot and humid.

define the general difference between an autotroph and a heterotroph
Answer:
Explanation:
If we break down the word autotroph, auto means “self” and troph means "feeding" or nourishment. However, when we break the word heterotroph, we get hetero- meaning other, and troph meaning feeders.
This is the critical difference between these two groups. Autotrophs synthesize or make their own food whereas, heterotrophs cannot make their own food thus have to rely on others by eating or absorbing others. For example, plants are autotrophs because they can make their own food using photosynthesis, whereas, humans are heterotrophs because we have to eat others to survive.
Answer:
autotrophs are organisms that can produce their own food from the substances around them using light or chemical energy
heterotrophs cannot synthesize their own food and rely on other organisms plants and animals for nutrition
Explanation:
Mutations that neither benefit nor harm the organism have _________ effect on the organism's survival.
A. a positive
B. a negative
C. an aggressive
D. a neutral

Which of the following means a hormone that aids in growth of gonads?
Glycogenesis
Thyrotoxic
Pancreatitis
Gonadotropin
Answer:
thyrootoxic
Explanation:
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 homones are 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.

Answer:
Bat boxes at homes provide housing to insect-eating bats which has two major positive effects on the environment:
Bat boxes provide bats a natural habitat and they act as natural pest control in the environment. They are very helpful for reducing or controlling the population of mosquito and balance the food chain in the environment.Bat is known as very good pollinators which helps in the pollination of flowers or spread their seeds. So bat boxes at home increase pollination in nearby areas and increase biodiversity in the environment.Hence, bat boxes at houses have a positive effect on the environment.

The image shows the path of a ball that’s thrown.
At positions (A,B,C, or D) and (D,E,F, or G), kinetic energy is maximum. At position (B,C,D,or E), potential energy is maximum.
At position (A) and (G), kinetic energy is maximum. At Position (D), potential energy is maximum.
At point A and G kinetic energy will be maximum while Potential energy is maximum at point D.
Kinetic energy (KE) is initially provided to the ball while it is still in contact with the throwing hand. Once the ball leaves the hand there is no input of energy. As the ball rises the KE is transformed to gravitational potential energy (GPE). This GPE is effectively stored in the height of the ball.Now, when the ball falls back to the ground its potential energy is transformed into kinetic energy, which will continue increasing as it gains momentum, until it finally collides with a surface.Learn more:
