You are studying a variety of pea plant that has either red flowers or white flowers. When you cross true-breeding red-flowering plants with true-breeding white-flowering plants, you get all red-flowering plants in the F1 generation. If you then allow the F1 plants to self-fertilize, you observe that 75% of the F2 plants are red-flowering plants, while 25% of the F2 plants are white-flowering plants. Next you make 640 different monohybrid crosses and decide to analyze only the first 8 plants produced from each of these crosses (i.e. a total of 5120 progeny plants total). How many of these crosses would be expected to produce 6 red plants and 2 white plants?
Answer:
approximately 200
Explanation:
From the question, we have
probability of red = 0.75
Probability of white = 0.25
We are required to find the probability of 6 red + 2 white plants offspring and after we do we multiply it by 640
We will solve this using the binomial theorem method
(a+b)⁸ = a⁸+8a⁷b+28a⁶b²+56a⁵b³+70a⁴b⁴+56a³b⁵+28a²b⁶+8a¹b⁷+b⁸
The required probability is 28a⁶b²
a = 0.75
b = 0.25
= 28 x 0.75⁶ x 0.25² x 640
= 28 x 0.178 x 0.0625 x 640
= 199.36
Which is approximately 200 crosses would be needed

Conjugation involves a transfer of genes
Answer:
Conjugation involves a transfer of genes
Explanation:
Conjugation is a transfer of DNA from a living donor bacterium to a living recipient bacterium by cell-to-cell contact. In Gram-negative bacteria it involves a conjugation pilus. ... Conjugative transposons carry the genes that enable mating pairs to form for conjugation.

J.S. Hart (Can. J. Zool. (1956) 34, 1, pp. 53-57) described seasonal changes in insulation of the fur of nine species of arctic and North temperate zone mammals. Relative seasonal changes ranged from 12 to 52% of the winter coat insulation value. Absolute changes were greatest in the largest mammals with thickest fur. Indicate if the following statements that are true or false.a. Increasing fur thickness would reduce conduction between the animal and the environment True or Falseb. Animals with thicker fur compared to those with thinner fur have different metabolic rates when measured at the same ambient temperature below the thermal neutral zone (TNZ). True or falsec. Endothermic mammals are most often classified as homeotherms. True or falsed. Fur does not affect the rate of convective and conductive heat loss in the cold. True or falsee. Changes in fur thickness is associated with an expression of a unique phenotype that optimizes fitness for a given environmental temperature.
True or false
Answer:
a. True
b. True
c. True
d. False
e. True
Explanation:
The fur plays a critical role as an insulator and it may be a greater thickness during the winter. The fur allows the animals to reduce their heat loss, thereby thicker fur may serve as an additional layer of insulation during the winter. Endothermic animals such as birds and mammals are capable of maintaining a constant body temperature independent of the environmental conditions. In a similar way, the homeothermic animals are able to maintain stable body temperature by regulating their metabolic processes (i.e., also mammals and birds can be classified as homeothermic animals). The study above cited (Hart, 1956) was aimed at collecting comparative information to support the role of fur as insulation in Canadian mammals and thus understand seasonal acclimatization in general. In this regard, Hart concluded that although seasonal differences could be observed in all species analyzed, the greatest absolute changes were observed in larger animals (that is, animals having the thickest fur).

Question 8 (1 point)
Which are the two highest (largest) level taxa in the Linnaean system?
Answer:
Explanation:
The most significant characteristics (attributes) of a taxon in biological systematics are considered [23] diagnosis, rank and volume. As the classification changes, the characteristics of taxa may change (in different systems, for example, taxa of the same size may have different diagnoses, or different ranks, or occupy a different place in the system) [24].
When identifying taxa, it is often recommended, in addition to the principle of exclusion of polyphily, to follow the principle of optimal diagnosability (which is taken into account when determining the volume and boundaries of each taxon) and the principle of unity of the level of diversity and isolation of taxa of the same rank. In practice, these two principles are not always observed.

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each?
Answer:
Hope this helps :)
Explanation:
Mitosis is the process by which cells duplicate.
Meiosis is a similar process which is just used to make reproductive cells such as eggs or sperm.
In mitosis, the cell DNA arranges into 46 chromosomes, duplicates, and then divides into two new cells.
In meiosis, the same duplication occurrs except four cells are created, each with only 23 chromosomes. (You know how you get half of them from each parent? This is so that the offspring have genetic variation.)
Another thing to notice about meiosis is that the cells are not identical like in mitosis, which simply duplicates them. Furthermore, in males all four sex cells are used as sperm but in females only one of these cells develops into an egg whereas the rest, called polar bodies, are reabsorbed into the body.
Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.

A man and woman have a son who is color blind, a recessive sex-linked trait carried on the X chromosome, but neither parent is color blind. The woman is now pregnant with their second child. Which of the following statements is true about the second child? A daughter will be color blind because the father is a carrier of the recessive allele. A son will be color blind because the mother is a carrier of the recessive allele. A daughter will not be color blind because the father is not a carrier of the recessive allele. A son will be color blind because the father’s mother must have been a carrier for recessive allele.
Answer:
A daughter will not be color blind because the father is not a carrier of the recessive allele
A man and woman have a son who is color blind, a recessive sex-linked trait
carried on the X chromosome, but neither parent is color blind therefore the
daughter will not be color blind because the father is not a carrier of the
recessive allele
Color blindness trait is sex-linked because the trait is carried on the
chromosomes. The female have XX chromosomes while the male have XY
chromosomes. The color blind trait in the son(XY) is as a result of the
woman donating the X chromosomes which is defective and the Y
chromosome came from the man which has no issues.
in this scenario, half of their male children will have normal vision while the
other half will be color blind. The father's X chromosome is normal and all the
girls(XX) will have normal vision but will have the color blind trait in their
chromosomes because the XX chromosome are donated from both the man
and woman.

3) The oceans and the atmosphere work together through global currents that do what?
A. Cycle energy and matter to support the biosphere
B. Cycle energy and matter to support plate tectonics
C. Cycle energy and matter to provide nutrients to secondary consumers
D. Cycle energy and matter to support the biosphere as a closed energy system
Answer:
The correct answer is D)
Cycle energy and matter to support the biosphere as a closed energy system
Explanation:
The earth as we know it is a closed energy system that is, matter cannot be introduced or removed from it. Sometimes, rare meterites enter into the system with minimal or no disruption.
Also, energy can enter and leave. The energy mostly referenced here is the sun.
Within the earths system, the lithosphere, hydrosphere, and biosphere materials and energy go through a cycle which helps to support life.
For example, water when heated up by the sun rises as vapour from the earth and oceans into the atmosphere where it cools and condenses. When it cools and condenses, it , in the form of rain, comes down on the earth and oceans. As rain falls down to the earth and runs off the rocks, rocks are broken down into smaller fragments and soils. The hydrosphere comprises of all water bodies on earth. Besides the vapours which are evaporated from the same into the atmosphere, when volcanoes erupt they also send vapourised water into the atmosphere.
So because the earth is a closed system, a change in one sphere effects a change in others. An example is a change in the water cycle.
Cheers
