Answer:
The hallux (big toe) of Carpolestes has synapomorphic features shared with the euprimate.The nail on the distal phalange is an example of a synapomorphic feature.Explanation:
The symplesiomorphic features are those shared by two or more organisms that inherited it from a common ancestor, but this trait is older in relation to those traits exhibited in other descendants of that same ancestor.The synapomorphic features are those shared by two or more organisms that inherited it from a common ancestor, and which evolved for the first time in it.There are more synapomorphic features shared with the euprimates. The nail on the distal phalange of the big toe and euprimates might be considered as a synapomorphic feature. It is quite different from the same nail of the tree shrew.

Species in which dark brown fur (D) is dominant relative to light brown fur (d). Using the Punnett square below, predict the frequencies of the genotypes and phenotypes of the offspring from dark brown parents two who are heterozygous (Dd genotypes).
Answers
Answer:
Genotype frequencies25% DD
50% Dd
25% dd
or
1 DD: 2 Dd: 1 dd
Phenotype frequencies75% Dark brown, 25% light brown
or 3 dark brown: 1 light brown
Explanation:
Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.
D d
D DD Dd
d Dd dd
25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown, since it has two copies of the dark brown fur allele (DD)
50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown fur (d).
25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)

In which situation might a gene pool contain an allele that causes a lethal
disease?
A. If the allele is in the mitochondria
B. If the allele is expressed after reproduction has occurred
C. If the allele is on the Y chromosome
D. If the allele is expressed in its dominant form
Answers
correct answer is B; if the allele is expressed after reproduction has occurred.
The situation in which a gene pool contain an allele that causes a lethal disease is: (B) If the allele is expressed after reproduction has occurred.
When the allele is expressed after reproduction has occurred, individuals carrying the lethal allele can reproduce and pass on the allele before the disease is expressed. Since the disease may not manifest until later in life or after reproduction has occurred, the allele can persist in the gene pool without being selected against. Over generations, the allele frequency can remain relatively stable, leading to the presence of the lethal allele in the gene pool.
An allele can be defined as a variant form of gene. Alleles can exist in different forms due to changes in the DNA sequence. These changes can be substitutions, deletions, insertions, or other types of genetic mutations.

Answers
Answer:
The correct answer is - bogs.
Explanation:
Bogs or boglands is a wetland that is made up of dead organic matter such as dead plants or parts of the plants like mosses, majority time it is a thick carpet of sphagnum moss. All these form spongy peat which is stagnant.
Most of the water present in this wetland comes from rainfall instead of runoff or streams from the groundwater which makes it a wetland with a shallow area of water-saturated soil. This wetland is known for its less photosynthesis.

In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.
Explanation:
Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.
The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.
In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

What is the estimated age of Earth?
A.4.6x10^6
B.4.6x10^7
C.4.6x10^8
D.4.6x10^9
Answers
Answer:
D: 4.6 x [tex]10^{9}[/tex]
Explanation:
4.6 x 10^{9} = 4,600,000,000
Earth is approximately, 4.6 billion = 4,600,000,000 = 4.6 x 10^{9}
The estimated age of Earth is 4.6x10⁹ years (D).
Scientists estimate the age of Earth through various methods, including radiometric dating of rocks and minerals. By analyzing the isotopes present in rocks and minerals, scientists can determine the decay rates of radioactive isotopes and calculate the time since the formation of those rocks.
Based on extensive studies and evidence, the current estimated age of Earth is approximately 4.6 billion years (4.6x10^9 years). This estimation is supported by multiple lines of evidence, including radiometric dating of rocks from different geological formations, lunar samples brought back from the Moon, and meteorites.
The age of 4.6 billion years is consistent with the age of the oldest rocks found on Earth's surface and the ages of the Moon and meteorites, which are believed to have formed around the same time as Earth. These dating methods provide a reliable framework for understanding Earth's geological history and the processes that have shaped our planet over billions of years.
It's important to note that scientific estimates and understanding of Earth's age continue to evolve as new evidence and research emerge. However, the current consensus among scientists is that the age of Earth is approximately 4.6 billion years, as indicated by extensive geological and radiometric dating studies.

What is the function of a pollen tube?
to lead sperm cells into the ovary
to create more pollen
to create sperm cells
to lead egg cells to the sperm cells
Answers
Answer:
The function of the pollen tube is to lead sperm cells into the ovary.
Explanation:
In angiosperms, the pollen tube is a structure formed when the pollen grain comes into contact with the stigma and germinates, producing a tubal extension that is related to the embryonic sac where the female gametophyte is found.
The function of the pollen tube is to conduct the male gametophyte —which is found in the pollen— to the embryonic sac, in order to come into contact with the oosphere and produce fertilization.
The other options are not correct because the pollen tube:
Do not create more pollen. Do not create more male spermatophytes. Does not lead the eggs to the male spermatophytes.Answer: to lead sperm cells into the ovary .
Explanation: There needs to be a way for the sperm cells formed by the pollen's generative nucleus to reach the egg cells that are found in the ovary.

2. What fluvial landform is A?
Answers
Answer:
The landform marked with A is an ox-bow lake.
Explanation:
In the image, we can see a river and another fluvial landform right next to it. The river is meandering, moving through the plain in a zig-zag manner. The landform next to it has a half-circular shape, and it seems as it has been attached to the river until recently. In fact, the landform next to the river has been a part of the river until recently, but because of moving too far away from the base it became detached.
The landform in question is an ox-bow lake. This is a lake that has a short lifespan, and it usually has a half-circular shape, being just a few meters away from the river from which it formed. Initially, the ox-bow lake was actually part of the river and its meandering, but as the erosion was moving the water further and further away from the base of the river bed, the water was moving harder and harder, so naturally, the water moves in a direction where it is easier to do so. Little by little, the river starts to move in another direction, closer to its base, and the part of the meander that went too far away gets detached, thus forming an ox-bow lake.

Answers
Answer:
Increasing carbon dioxide concentration increases the rate of photosynthesis as carbon dioxide (CO2) is a limiting factor.
Explanation:
Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.
The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.

objective by raising the oil objective a little to avoid the damage to objective lens. Critique his
technique.
Please
Answers
Answer:
The observed image will not be sharp
Explanation:
When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).

Answers
Answer:
If a student breathes through a 3 feet long glass tube it will affect the physiology of the student in various ways such as a change in blood pH, urine pH, and rate of respiration.
It will result in an increase in the normal volume area of the trachea and bronchi as it is a closed system as a face mask. The increase in this dead volume are will result in double the volume of CO2. Decrease the pH of the blood.
When asked to breathe through 3-foot long glass tube there would reduced oxygen available to the tissue (hypoxia) which had the following effects discussed below.
Hypoxia occurs when there is reduced oxygen available to the body tissues.
When asked to breathe through a 3-foot long glass tube, it can lead to hypoxia.
The effect of hypoxia include the following:
Blood pH: Due to increase in anaerobic respiration in the tissues, lactate production increases leading to a fall in blood pH. Urine pH: Hypoxia leads to increase in renal sodium excretion which helps acid-base balance of the body fluid. Respiratory rate: There is significant increase in respiratory rate to compensate for the decreased tissue oxygen levels.Learn more here:
