what is mutation? why are mutations more serious when they occur in a sex cell?
Answer:
A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Mutations in sex cells are more serious because they are heritable and affect the next generation.

the problem is CAN PLANTS STOP SOIL EROSION?
what can we put a title for this problem
what is the hypothesis for this problem
please help
Answer:Name for project.SOIL SAVERS. plants can stop soil erosion because the roots in plants keep the soil intack. this has already proven true by scientists and farmers. planting plants that has a large root system keeps more soil in. planting carrots and potatoes does not help keep the soil still because they have small root system.
Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic
isolation allow for the change of gene pools over time?
O Biogeographic isolation affects the random changes that take place within gene pools.
O Biogeographic isolation causes changes in gene pools that result from populations being separated.
O Biogeographic isolation determines who will win competition for mates
O Biogeographic isolation determines the time that populations will breed

5. Knowing that acid rain has a pH of 2-3, would you conclude that crop species with a narrow soil pH range are in trouble? Is acid rain a problem for plant species and crops?
Answer:
Yes
Explanation:
Unless the crops acidity range is that of the rain( which it wouldn't be) it would throw off the crops Ph balance and harm it.
Yes, crop species with a narrow soil pH range are potentially in trouble due to acid rain. Acid rain can have harmful effects on plant growth and productivity. The acidity of the rain can change the pH level of the soil, making it more acidic and less hospitable for plants.
What is acid rain?Acid rain is a type of rain or other precipitation that is unusually acidic and has elevated levels of hydrogen ions (low pH). It is caused by the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which then reacts with water vapor to form sulfuric acid and nitric acid.
These acids can fall back to the ground as acid rain or other forms of precipitation and can cause harm to plants, animals, and infrastructure. Acid rain can also contribute to soil and water pollution and can have negative impacts on human health.
Acidic soil can also release toxic substances, such as aluminum, which can further damage plant roots and reduce plant growth. In addition, acid rain can damage plant foliage directly, leading to reduced photosynthesis and reduced yields.
So, acid rain can be a significant problem for plant species and crops, particularly those with a narrow soil pH range.

Having freckles is a dominant trait, and not having freckles is a recessive trait. Which set of parents will not have any children with freckles? A. A mother with FF and a father with ff O B. A mother with Ffand a father with Ff O c. A mother with ff and a father with ff
As freckles are a dominant trait, they will not occur in the children with a homozygous recessive trait, i.e., ff. The correct option is C.
What are recessive traits?Recessive trait is a trait that really should be transmitted by both parents in order to be present in the offspring. Recessive features might exist in a person's DNA but not manifest in that individual.
As in the given case, F denotes dominance, and f denotes recessive character. Dominant trait always superimpose over the recessive one.
So, as freckles are a dominant trait, they will not occur in the children with a homozygous recessive trait i.e., ff.
Thus, the correct option is C.

Three terms used to describe organisms such as cows are:
MammalsHerbivoresRuminantsWhat is an organism?An organism, especially a cow, is a living thing. An organism is a singular living being that exhibits characteristics of life, such as the ability to develop, reproduce, respond to stimuli, and preserve homeostasis. Mammalia, a class of multicellular organisms including cows, forms the animal kingdom. Cows are complex biological entities with specialized sensory and digestive systems that enable them to live and thrive in their environment.
The following three terms are used to describe cow-like creatures:
Cows are mammals, which are warm-blooded animals with hair or fur and the ability to feed their young with milk.
Herbivores: Cows are herbivores, which means they only eat plants and no animal products like meat or dairy.
Cows are included in the class of herbivorous mammals known as ruminants, which have a four-chambered stomach.

If a female fruit fly is heterozygous with the allele for white eyes being recessive and the red eyes being dominant on the X-chromosome. She is crossed with a hemizygous red eyed male, what would be the expected ratio of male and female phenotypes if they were bred together?
Answer:
100% red eyes because there is 50% AA and 50% Aa.
Explanation:
To find the expected ratio of male and female phenotypes if they were bred together, you need to make a punnett square/table.
Female: A a
"A" is white eyes, which is RARE. "a" is red eyes, which is COMMON.
Male: A A
"A" is red eyes, which is COMMON.
Multiply Aa x AA by a punnett square.
GUIDE:
1. AA is common and does not carry the recessive gene of being white-eyed. 2. aa is rare and carries the recessive gene of being white-eyed.
3. Aa is common as being red-eyed since being red-eyed is dominant, but carries the recessive gene of being white-eyed.

white eyes are recessive in flies. can two red eyed flies have white eyed offspring
Answer:
Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.
Explanation:
For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.
In the case of the characteristic eye color of the flies :
Red eye (R) is dominant trait. White eyes (r) is the recessive trait.When both parents are heterozygous, their genotype is Rr
In Punnett Square it can see the result of the crossing of these individuals:
Punnett Square :
Rr X Rr
Alleles R r
R RR Rr
r Rr rr
In the offspring, the probabilities are:
50% heterozygous individuals Rr, with red eye phenotype. 25% pure dominant individuals RR, with red eyes 25% individuals with the recessive rr genotype, white eyes.This is the possibility of two red-eyed flies having white-eyed offspring.
