Answer: Crabs walk sideways because their legs only bend in that direction. muscles also work in pairs. One of these muscles simply pulls on the leg, and is dependent on the activation of another antagonistic muscle to regrow. In addition, this walking style can be related to the density of the water.

What did Mendel discover about the principles of heredity? Choose the two staments that apply.
Answer:
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes comes in pairs and are inherited as distincts units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominate or recessive traits.
how does gene regulation relate to the continuity of life
In order to determine the expected average offspring length, what do you multiply with your heritability
Complete question:
In a population of toads, the average body length is 30mm. Body length is variable and the narrow sense heritability for body length is 0.1 for this population. You cross a male of 20mm with a female of 22mm. In order to determine the expected average offspring length, what do you multiply with your heritability?
30mm 9mm 0.1 8mm -9mm -0,5Answer:
The correct option is -9mm
In order to know the expected average offspring length, OABL, we need to multiply the selection differential, SD ( -9mm) with narrow-sense heritability, h² (0.1).
Explanation:
Available data:
the average body length, ABL, is 30mmthe narrow-sense heritability, h², for body length is 0.1male of 20mmfemale of 22mmTo answer this question, we need to remember how can we calculate the selection differential and the heritability in the narrow sense.
We can get the selection differential, SD, by getting the difference between the mean value of a population length, ABL, and the mean value of the parents of the next generation, PABL. So, in this example the selection differential is:SD = (20mm + 22mm)/2 - 30mm
SD = 21 mm - 30mm
SD = - 9mm
The heritability in the narrow sense, h², for body length in the population ish² = body lengths of the offspring average/selection differential
But we already know the value of h². And we want to know the body length of the offspring. So we just need to clear the following equation.
OABL = ABDL + h² ( PABL - ABL)
where,
offspring average body lengths = OABLpopulation average body length = ABL = 30mmparents average body length = PABL = 22mmSelection diferential = SD = -9mmnarrow sense heritability = h² = 0.1OABL = ABDL + h² ( PABL - ABL)
OABL = ABDL + h² ( SD)
OABL = 30mm + 0.1 ( -9mm)
OABL = 30mm + (-0.9 mm)
OABL = 21 mm
In order to know the expected average offspring length, OABL, we need to multiply the selection differential, SD ( -9mm) with narrow-sense heritability, h² (0.1).

In what type of situations would random sampling (last lab) be useful?
In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.
It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.
This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.
One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.

What are cell products and why are they not a characteristic of life?
Answer:
When viewed together, these characteristics serve to define life. ... (This requirement is why viruses are not considered living: they are not made of cells.
Cell products are the products produced by the cell organelle and are not a characteristic of life on their own as they can not perform all the essential functions and processes.
Cell products in cell biology are the products that are produced by various cell organelles such as the Golgi body and these products are part of the cells and help cells to perform specific functions.
The characteristics of life are the traits that are shown by all organisms that are:
Cellular organization,the ability to reproduce,growth & development,energy use,homeostasis,response to their environment,the ability to adapt.Thus, the cell products are manufactured by cell organelles and do not consider characteristics of life as the cell is the unit of life.
