Phenotypes are usually the result of a combination of genes and influence of the environment.
Explanation:
Genes and the environment both affect phenotype.
Phenotypes are usually the result of a combination of genes and the influence of the environment.
What is genes?
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.
During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gene–environment interactions. Some genetic traits are instantly visible, such as eye color or the number of limbs, and some are not, such as blood type, the risk for specific diseases, or the thousands of basic biochemical processes that constitute life.
Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotypical traits. Usage of the term "having a gene" (e.g., "good genes," "hair color gene") typically refers to containing a different allele of the same, shared gene.Genes evolve due to natural selection / survival of the fittest and genetic drift of the alleles.

What are the causes of variations ? please explain thi also
Answer:
variation can be caused by mutation and other things
Explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light or cigerette smoke
➜ Following are the causes of variations:
Dual percentage: Offsprings inherit some features from mother and some from father. Hence no offspring will exactly resemble to either of the parent or each other.Mutation in gene or chromosomal pattern also causes variations.
Do you think that sharks and dolphins' similarities (body shape, fin, and flippers) are homologies or analogies
Answer:
homologous* or analogous*. You spelled them wrong :)
I believe they are homologous because they more than likely share ancestry. They are underwater animals with the same... everything pretty much.

3. Si sales de tu casa y recorres 5 metros de distancia. ¿A qué distancia te
desplazaste?
Answer:
5 metros.
Explicación:
Si sale de su casa y camina 5 metros, significa que está a 5 metros de su casa porque cubre 5 metros de distancia. La distancia es la longitud que recorre un cuerpo entre dos puntos. Aquí un punto es la casa y el otro punto es la persona, por lo que si calculamos la longitud, encontramos que el individuo cubre 5 metros por lo que podemos concluir que el individuo está a 5 metros de su casa si camina 5 metros de su casa. casa al exterior.

Inherited traits are described by probabilities. When experimenting on inherited traits, why is it important to have a large sample size?
Tysm! I love you<33
Answer:
results will be more accurate if there is a larger sample size.
No matter what research is, the larger sample size is, the more accurately will be the results and vice versa. The larger samples increase a chance of significance because they reflect the population mean more reliably.
With small sample, the chance for false conclusions is higher.

2. Tania went outside and made two observations of the Moon that were several days apart. Her
observations are shown in the diagram above. The light part of the Moon appeared to get larger over
time. Why did this happen?
The reason why the light part of the moon appeared to get larger over time is because between the first observation and the second observation, the moon moved so that Tania was able to see not of the half that faces the sun.
It should be noted that from the observation that Tania made, the light part of the moon appeared to get larger over time.
The reason for the above want due to rotation but rather because the moon moved so she was able to see not of the half that faces the sun.

Property of water that makes transpiration to occur
Answer:
cohesion
Explanation:
One of water's most distinctive properties is cohesion—that is, the tendency of water molecules to "stick" to one another. In plants, this cohesion results in columns of water that stretch through the plant's xylem, from the roots all the way to the leaves.
