In a certain plant, yellow leaves are dominant (Y) and red leaves are recessive (y). A plant with genotype Yy and a plant with Yy are crossed. If they have four offspring, how many would you predict would have red leaves?

Answers

Answer 1

Answer: 1 plant. This is because offspring will only have red leaves if it receives yy, and there is a 25% chance of this, so 1/4 of the offspring will be predicted to have red leaves.

Answers

Answer;

C. To gather information about the natural world, to explain natural phenomena, and to allow reasonable predictions of future events.

Explanation;

-Science is an organized way of gathering and analyzing evidence about the natural world. Science aims to explain and understand. Science as a collective institution aims to produce more and more accurate natural explanations of how the natural world works, what its components are, and how the world got to be the way it is now.

-One goal of science is to provide natural explanations for events in the natural world. Science also aims to use those explanations to understand patterns in nature and to make useful predictions about natural events.

C) To gather info about the natural world, to explain natural phenomena, and allow reasonable predictions of future events

Chlorophyll traps _____ from sunlight.a. oxygen
c. hydrogen
b. energy
d. glucose

Answers

The correct answer is b - energy

Chlorophyll is a green pigment that has light absorbing ability. Light from the sun contains energy in the form of photons.

The photons are trapped by chlorophyll and are used to provide power to split water molecules in the leaf in the process of photosynthesis.

Because chlorophyll is a pigment that absorbs light, it is called a photoreceptor. By absorbing light energy, chlorophyll is vital in the photosynthesis and without it, green plants would not be able to get power to run photosynthesis.

what determines the color of your skin? a. number of melanosomes b. type of melanin c. amount of melanin d. all of the above

Answers

Answer:The color of your skin is determined by all of the factors listed: the number of melanosomes, the type of melanin, and the amount of melanin.

Explanation: 1. The number of melanosomes: Melanosomes are structures found in skin cells that contain melanin. The more melanosomes present, the darker the skin color can be. For example, individuals with darker skin tones generally have more melanosomes compared to those with lighter skin tones.

2. The type of melanin: There are two main types of melanin - eumelanin and pheomelanin. Eumelanin is responsible for brown and black pigmentation, while pheomelanin contributes to red and yellow pigmentation. The ratio of these two types of melanin in your skin can affect its color.

3. The amount of melanin: The amount of melanin produced by melanocytes, the specialized cells in the skin, also influences skin color. Higher levels of melanin result in darker skin tones, while lower levels result in lighter skin tones. This variation in melanin production can be influenced by genetic factors, sun exposure, and hormonal changes.

In summary, the color of your skin is determined by the number of melanosomes, the type of melanin present, and the amount of melanin produced. These factors interact to create the wide range of skin colors observed in different individuals
