Green plants use light energy to grow. What would happens to a plant in dark green house if they were lit only by green light
Answer:
It will not photosynthesized.
Explanation:
A plant in a dark green house will not photosynthesized because for photosynthesis to occur, plants must be able to absorb red light and blue light energy in order to produce carbohydrates. The green light from the green house of plant placed there is a reflection of the green pigment i.e chlorophyll that the plant possessed. This can not allow photosynthesis.

Cross a person who does not have freckles and is heterozygous for dimples with a person who has
freckles (but her mom does not) but no dimples.
1. What is the probability that these parents will have a child with dimples?
2. What is the probability that these parents will have a child with freckles?
3. What is the probability that these parents will have a child with dimples and freckles?
Answer:
1. 1/2
2. 1/2
3. 1/4
Explanation:
Let the allele for freckles be A or a while that of dimples be B or b.
A person without freckles but heterozygous for dimples = aaBb
A person who has freckles (whose mother has no freckles) but no dimples = Aabb
aaBb x Aabb
Offspring
4 AaBb - freckled and dimpled
4 Aabb - freckled and non dimpled
4 aaBb - non freckled and dimpled
4 aabb - non freckled and non dimpled
1. Probability that the parents will have a dimpled child = 8/16 or 1/2
2. Probability that they will have a child with freckles = 8/16 or 1/2
3. Probability that they will have a child with freckles and dimples = 4/16 or 1/4

What is one event that may occur during Telophase I?
An event that may occur during Telophase I is: the nucleus of each cell may reappear as two independent cells are being formed.
Meiosis can be defined as a type of cell division or duplication that occurs in all body cells found in living organisms, through which a single cell divides twice to produce four (4) haploid cells (gamete).
Basically, deoxyribonucleic acid (DNA) must replicate before meiosis can occur in all body cells found in living organisms.
Generally, the phases or steps that occur during meiosis include:
Prophase I.Metaphase I.Anaphase I.Telophase I.Prophase II.Metaphase II.Anaphase II.Telophase II.Sometimes, the nucleus of a single cell may reappear when two (2) independent cells are being formed during Telophase I.

Write a short paragraph that explains the relationship between the terms "chromosome," "gene," "DNA," and "allele."
Answer: Genes appear throughout the length of each chromosome, and each chromosome pair has a unique set of genes. ... In a diploid organism, the two corresponding genes in a chromosome pair, or alleles, might be identical or might have different base sequences. Each parent contributes one allele in each pair.Alleles are different forms of same gene. Genes are linearly arranged on chromosomes. Chromosomes contain genetic material of cell i.e. DNA. So chemically alleles, genes, chromosomes are all DNA !

How do tropisms help plants survive?(1 point) Plants grow together with other plants. Plants create their own food using chlorophyll. Plants limit their needs in harsh conditions. Plants grow toward things they need.
Answer:
Plants grow toward things they need.
Explanation:
Tropisms help plants to survive by ensuring that they grow towards what they need.
Tropism is defined as the growth of plants or their organs towards or away from external stimuli such as light, moisture, gravity, etc. This type of growth ensures that plants are able to grow towards what they need and away from what they do not need.
For example, the stems of plants generally grow towards light because light is necessary for photosynthesis. Similarly, the roots of plants always grow downward as a positive response to gravity in order to ensure that the plant is firmly supported in the soil. The roots of plants will also grow towards moisture because of the essentiality of water for plant's metabolic processes.

Answer:
A. Basic senses
Explanation:
Physical properties include colour, shape, size, these can be detected with sight, touch and more
Physical properties are typically things you can detect with your basic senses. Therefore, the correct option is option A.
The features or attributes of matter that can be viewed or quantified without altering the substance's identity are called its physical properties. Usual methods for identifying these characteristics include sight, touch, taste, smell, and hearing. Without executing any chemical reactions or significantly changing the substance, we can learn information about the physical condition or behaviour of a substance by using our senses. Overall, physical attributes give us important knowledge about the composition and behaviour of matter that we can experience with our five senses.
Therefore, the correct option is option A.

The appearance of the moon changes in a predictable pattern that lasts approximately 28 days.the changes in appearance are called phases of the moon.what is the main cause of the moon phase
Answer:
The main cause of the moon phases is the changing position of the moon in relation to the sun and the earth.
Explanation:
The moon phases are the perception of the part of the moon that is visible, when observed from the earth. When it is completely visible it is called full moon, when it cannot be seen it is called new moon and the phases between one and the other are called crescent and waning quarters.
The moon can be visible when it receives illumination from the sun but, due to its changes in position with respect to the earth, this illumination can be complete, partial or absent, which defines each of the phases.
When the moon completes its four phases it is called the lunar cycle, and it has an estimated duration of 29.5 days.
Where would you find the hydrophilic amino acid sequences if a protein molecule is placed in water? Explain why. (Hint: EXPLAIN in your own words.)
Answer:
The correct answer is - on the surface.
Explanation:
Proteins are made up of long chains called polypeptide chains made up of amino acid residues linked together. These amino acid residues could be hydrophobic or hydrophilic in nature. Hydrophilic is the nature of water-loving whereas hydrophobic is that tries to avoid water.
So, if a protein placed inside the water the hydrophilic amino acids will be present on the surface of the protein, and hydrophobic amino acids present inside of the protein structure.
