hi guys I need help with those questions can somebody help me please am doing a science fair project
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.

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.
Explanation:
Explain why it makes sense to use the word translation to describe protein synthesis and why it would not make sense to use the word translation to describe mRNA synthesis?
Answer:
The application of the word translation makes sense at the time of describing the synthesis of protein as the language of nucleic acids is transformed into the language of polypeptides by the phenomenon of translation. On the other hand, it will not be suitable to describe the synthesis of mRNA using the word translation as the nature of the biomolecule stays similar because both the DNA and the product of DNA, that is, mRNA are nucleic acids.

What are 3 terms used to describe organisms such as cows
Answer:
animals
mammals
vertebrate
Explanation:
cows have a backbone so they are a vertebrate
cows have hair so they are mammals
and the are animals just like every other living thing
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.

B. Crossing over will result in new genetic material.
C. Chromatids will have just moved toward opposite poles.
D. One much larger cell will be produced through nuclear fusion.
Answer:
i think its b i could be wrong
Explanation:
The correct model shown is Crossing over will result in new genetic material.
What is crossing over?
When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the development of egg and sperm cells.
This process leads to novel allele combinations in the gametes (egg or sperm) produced, ensuring genomic variety in any offspring born.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father.
Therefore, The correct model shown is Crossing over will result in new genetic material.

Sclerenchyma
Answer:
The correct answer is - Sclerenchyma
Explanation:
Sclerenchyma are the dead cells with narrow lumen lignified cells. These dead cells has numerous pits that helps in trading the various substances to neighboring cells. At matuarity, hese cell lack the protoplast so therefore called dead cells .
Sclerenchyma cells are lignified which makes them thick and these cells help in the supporting the plants. These cells are impereable to almost everything gases, substances and many more.

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.

Answer:
The appropriate alternative is Option b (Apurinic site repair).
Explanation:
Although these antibodies eliminate compromised DNA bases through midriff of N-glycosylic attachments, maintaining perhaps an apurine or perhaps even apyrimidine site today.RecA connects towards DNA damage as well as precipitates recombinant restoration through doulas branch fracture pairing or daughter strand difference restore.Other solutions aren't relevant to the situation in question.
