receives information about your body
c.
signals a response to stimuli
b.
maintains homeostasis
d.
all of these are nervous system functions
Answer:
Option A, The two forms interbreed successfully where their habitats overlap
Explanation:
The two species of warbler i.e myrtle warbler and Audubon's warbler are capable enough to interbreed when their habitat overlap by maintaining postzygotic selection against hybrids.
These two warblers do not interbreed freely but they do so on routine basis in a narrow zone at the northern edge of the Audubon form’s range in western Canada to hybridize
Hence option A is correct
The earth's temperature is not affected by solar radiation.
The earth is heated by terrestrial radiation.
The earth's temperature is not affected by terrestrial radiation.
The following answer is correct :
The earth is heated by terrestrial radiation.
Terrestrial radiation is a radiation emitted by naturally radioactive materials present on Earth including uranium, thorium etc. Solar radiation produced from the sun also heats up the environment but not directly. But rather it is heated by the terrestrial radiation that the planet itself emits.
B) roan × roan
C) white × roan
D) red × roan
E) The answer cannot be determined from the information provided.
The cross between roan (heterozygous) cattle would produce offspring in the ratio of 1 red: 2 roan: 1 white. This is a scenario of a monohybrid cross, yielding a 1:2:1 ratio in offspring.
In this genetics problem, 'R' represents red coat color gene, 'r' represents white coat color gene, and the combination 'Rr' gives a roan coat color. To get a 1:2:1 ratio of red:roan:white, the cross must be between two heterozygotes, or roan-colored cattle (Rr × Rr). So, the correct option is B) roan × roan. This type of cross, known as a monohybrid cross, yields a genotypic and phenotypic ratio of 1:2:1 (1 RR: 2 Rr: 1 rr) in the offspring.

b. they exhibit the same basic cell wall.
c. they perform the same mode of reproduction.
d. they have dna within their nucleus.
Answer;
D. they have DNA within their nucleus.
Explanation;
-According to evolutionary theory, diverse groups of animals evolve from one or a few common ancestors and the mechanism by which this evolution takes place is natural selection.
-Natural selection is the process by which traits that enhance survival and reproduction become more common in successive generations of a population.
-All forms of life are built of cells. A cell is the basic unit of the structure and function of living things. Living things may appear very different from one another on the outside, but their cells are very similar.
