A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. The soil in the area has become darker and closer in color to the black beetles. Which of the following will most likely occur?
Selective pressures will decrease the number of brown beetles.
Selective pressures will increase the number of brown beetles.
Selective pressures will decrease the number of black beetles.
The overall size of the beetle population will continue to decrease over time.
Answers
Answer:
the first option
Explanation:
As the soil gets darker, brown beetles become easily recognised by predators (like birds) and will be eaten. Black beetles however, are better camouflaged and will less likely be spotted by the birds. Black beetles will survive and interbreed, allowing the recessive allele to be passed on to upcoming generations.
Selective pressure is what makes the genetic pool shift toward a particular genotype with a particular phenotype (recessive black in this case) that gives the new generations a selective advantage. They're more likely to survive and reproduce. Survival of the fittest.
Genotype- the genetic makeup of an organism (eg: the recessive gene for black; bb)
Phenotype- physical feature of an organism as determined by the genotype (the colour black)
Selective pressures will increase the number of brown beetles. The correct option is 2.
What is Selective pressure?Any factor that reduces or increases reproductive success in a subset of a population may exert evolutionary pressure, selective pressure, or selection pressure, thereby driving natural selection.
Selection pressure can be defined as a force that causes an organism to evolve in a specific direction.
It is not a physical force, but rather an interaction between natural variation in a species and environmental factors that causes certain forms to have an advantage over others.
A beetle species can be either black or brown in color. A single gene determines the color of the beetle, and black is recessive to brown.
The soil in the area has darkened and taken on the color of black beetles. Brown beetle populations will increase as a result of selective pressures.
Thus, the correct option is 2.

b.) nondisjunction
c.) crossing over
d.) synapsis
Answers
Answer:
b.) nondisjunction......
A woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.
What do you mean by Chromosomes?Chromosomes may be defined as tiny, threadlike structures inside most cells of every organism, or living thing which carries the genetic information.
The presence of 3 X chromosomes indicates the condition of trisomy which arises as a result of non-disjunction.
When homologous chromosomes fail to separate at meiosis resulting in a germ cell containing 24 chromosomes rather than 23.
Therefore, a woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.

Scientists often use the analogy of a tree to describe the history of life on Earth. All organisms alive today, including archaea, bacteria, and eukaryotes, can trace their development to the same common ancestor or set of ancestors, which forms the base of the tree. Which statement provides the strongest evidence for the conclusion that all living things share common ancestry?
a. All living things perform either cellular respiration or photosynthesis
b. All living things use DNA as a genetic code to transmit information
c. All living things have vestigial structures that are remnants of structures found in ancestral species.
d. All living things are made of cells with approximately the same composition, size, shape, and function
Answers
Answer:
B
Explanation:
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to discover history of a living organism and to produce proteins, which are the complex molecules that do most of the work in our bodies

UAA is a codon that signals to stop making a protein, and so it is therefore called a ______
Answers
Answer:
stop codon
hope this helps, good luck :)
UAA is a codon that signals to stop making a protein, and so it is therefore called a stop codon.
What is a codon?Codon may be characterized as a sequence or collection of three consecutive nucleotides in a DNA or RNA molecule that significantly codes for a specific amino acid. These sequences of nucleotides give a signal to the start or end of translation.
A stop codon is also a sequence of three nucleotides (a trinucleotide) in DNA or messenger RNA (mRNA) that specifically signals a halt or inhibits to protein synthesis in the cell. Out of 64 different trinucleotide codons, there are only three stop codons are there, namely UAA, UAG, and UGA.
The start codon is the initial set of codons in an mRNA transcript that is translated by a ribosome. CAG is a start codon. Nonsense codons also play an important role.
Therefore, UAA is a codon that signals to stop making a protein, and so it is therefore called a stop codon.

Which graphic organizer best represents asexual reproduction? Which graphic organizer best represents sexual reproduction? Explain your answers.
Answers
The one with one parent and five offspring represents asexual reproduction. Asexual reproduction only requires one parent, so the offspring are genetically identical to the parent. The advantage is that organisms can reproduce much quicker using this method.
The organizer with two parents and one offspring represents sexual reproduction. Again, sexual reproduction requires two parents.
This molecule provides stability to the phospholipid bilayer and without it the membrane would easily fall apart.
Answers
Answer:
The correct answer is - cholesterol molecules.
Explanation:
Cholesterol molecules are the molecules that acts as a bidirectional regulator for the lipid bilayer as it provides fluidity by raising the melting point of the membrane at high temperature and stabilize the membrane.
On the other hand, it also prevents the membrane from clustering or being tough or stiff by intercalates between the phospholipids at low temperatures. Therefore it is the molecule that provides stability to the membrane.

Describe THREE examples of the effect of altitude on animals.(life science)
Answers
Altitude is an elevation from the sea level. It plays an important role in animals as it affects the respiratory rate, pressure on the cells, and homeostasis.
What is the respiratory rate?Respiratory rate is the breathing that involves the inhalation and exhalation of gases through the respiratory system. The breathing rate is reduced due to decreases in oxygen transport at a higher altitude which causes fatigue.
At higher altitudes, the pressure is more and in turn, affects the cells as the body also maintains an osmotic pressure to balance the fluid and internal organs. As the altitude increases the temperature drops which affects the homeostasis of the body resulting in more use of energy to keep warm.
Therefore, altitude affects respiration, cell pressure, and homeostasis.
