Mendelian inheritance states that traits are determined when offspring receive
from
linn a different trait.
i need help
Answer: Mendelian inheritance states that traits are determined when offspring receive alleles for each trait from either of the parents. Traits can be dominant, which means they can be seen and are capable of masking a different trait. ... Alleles are different versions of the same genes in an organism
Explanation: Allels can be either recessive or dominant.

How does camouflage help an organism survive?
Answer:
they camouflage into environment to blend in and to look the same as whatever they are on or in this stops them from being recognized
Answer:
Organisms use camouflage to mask their location identity and movement. This allows prey to avoid predators, and for predators to sneak up on prey
Explanation:
which is true regarding the process of meiosis I?
A) chromosome Number is reduced from diploid to haploid
B) sister chromatids in a cell undergoing are always identical
C) Most homologue pairs do not have any crossovers during prophase I
D) sister chromatids separate to opposite ends of the cell
Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)
Explanation:
In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.
Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.
A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:
--> the chromosomes replicate once and
--> the nucleus and cell duplicate ( divide equally) twice.
As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.

Name the hormone released when the blood glucose concentration is too low
Explanation:
Glucagon
vbbxfj be vcxxxcghjhhg
Answer:
Glucagon is released to stop blood sugar levels dropping too low (hypoglycaemia), while insulin is released to stop blood sugar levels rising too high (hyperglycaemia). The release of glucagon is stimulated by low blood glucose, protein-rich meals and adrenaline (another important hormone for combating low glucose).

How are the sensory receptors for hearing and touch similar?
Answer: salah it is good for ur breath.
Explanation:
The sensory receptors for hearing and touching are similar because the sensory receptors take the message from that sensory area, and most of the stimulus is vibration.
What are sensory receptors?The receptor is present on the cell surface, and the sensory receptor is present on sensory areas such as the skin, ear, and so on, and most of the time the stimulus is carried out by the sensory neuron to the brain or spinal cord. The sensory receptor takes the stimulus, and later, in the spinal cord or in the brain, it is further programmed and the action is generated. The action is generated by the sensory stimulus, and then, with the help of the motor neuron, the action is seen.
Hence, the sensory receptors for hearing and touching are similar because the sensory receptors take the message from that area, and most of the stimulus is vibration.

The red line represents the actual bear population, while the blue line shows the predicted population. Why doesn't the actual bear population ever match the exact carrying capacity?
Answer:
Explanation:
Predicted populations are ideal circumstances and do not account for many of the external factors that can affect the data in the current study. Therefore, many times the actual population is either lower than the population or exceeds it but is almost never exact. This can be due to weather conditions that cause a large portion of the population to die out, excess food, hunters, etc. Many factors can drastically affect whether the population is dying or thriving.
Which of these is an example of a biotic factor that could limit a community in an ecosystem?
A. A drought occurs for several months.
B. New predators move into the ecosystem.
C. A hurricane passes through an ecosystem.
D. Living space is lost due to human activities.
Answer:
B. New predators move into the ecosystem.
Explanation:
A, C, and D are all abiotic (nonliving) factors that could limit a community in an ecosystem.

Movement of the particles across the membrane stops when the concentration gradient no longer exists, the particles will continue to diffuse due to random motion
Answer:
Once the concentration gradient no longer exists, particles will continue to diffuse due to random motion.
Explanation:
When there is a permeable membrane between two solutions with different concentrations, the concentration gradient will go from the compartment with more particles to the one with fewer particles to valance the concentrations on both sides of the membrane. Once the concentrations are equal, particles will still randomly move from one side to the other, but the number of particles that move to one side is almost the same as the number of particles that move to the other, so there is still valance and the same concentration in both sides.

Explanation:
Mutations are genetic changes in the DNA sequence of the genome in a particular organism. Mutations are caused by adding one or more extra nucleotides into the DNA (i.e. insertions), deleting nucleotides (i.e. deletions), or replacing nucleotides (i.e., substitutions). Due to the diverse nature of mutations, it is expected that they have different effects on the gene product (i.e., the resulting protein). For example, a deletion or an insertion, which are collectively are referred to as 'indels' mutations, may generate frameshift mutations that shift the way the DNA sequence is read. Moreover, if a nucleotide letter is written backward, it doesn't change the final product (i.e., the nucleotide sequence), which is represented in the example with the C option.
