Answer: 3 individuals.
Explanation: Recombination frequency is the proportion of offspring who will inherit the recombinant genes.
The F1 progeny has genotype CcDd. When crossed with an individual with genotype ccdd, F2 generation can be CcDd or ccdd in a 50/50 probability.
The recombinant frequency is 0.4, which means in a total of 10 individuals of F2, 4 will be recombinant, so 6 will be parental, i.e., will carry the same genes of their parents.
From the population of 6, half of them will carry dominant genes for both features, so:
6 x 0.5 = 3
Therefore, from 10 individuals of F2, we expected 3 to be dominant for both genes.

describe the relationship between mitosis and the other stages of the cell cycle.
girl all you gotta do is use Google..
"Actively dividing eukaryote cells pass through a series of stages known collectively as the cell cycle: two gap phases (G1 and G2); an S (for synthesis) phase, in which the genetic material is duplicated; and an M phase, in which mitosis partitions the genetic material and the cell divides."
What are the limitations of uranium-238 dating? How did you overcome
its limitations?
Answer:
4
Explanation:
Answer:
Uranium 238 is only found in igneous or volcanic rocks. So no fossils can be dated directly using U 238. Because of the huge differences in the half lives of Carbon 14 and Uranium238 they cannot be used together. Carbon 14 can only be used to date fossils of a very recent age.

Which of the following "Best Management Practices" is NOT a widely used sustainable farming practice?
Answer:
Rotating crops and embracing diversity. ...
Planting cover crops. ...
Reducing or eliminating tillage. ...
Applying integrated pest management (IPM). ...
Integrating livestock and crops. ...
Adopting agroforestry practices. ...
Managing whole systems and landscapes.
The best practices for sustainable agriculture are the rotation of the crops, the maintenance of the diversity of the crops to avoid soil sterility, and the avoidance of chemical pesticides.
What is sustainable agriculture, and how does it affect soil?Sustainable farming is the most effective way to practice farming because it does not harm the soil while providing fertility, and many practices are used, such as using earthworms and compost instead of chemicals. Usage of the rotation crops; different crops should be cultivated rather than focusing on the single crop; more effective ways of watering, etc.
Hence, the best practices for sustainable agriculture are the rotation of the crops, the maintenance of the diversity of the crops to avoid soil sterility, and the avoidance of chemical pesticides.

If you find a reptile fossil buried and lithified among mud and decayed plant material, what type of depositional environment might you infer while the animal was still alive?
Answer:
The correct answer is - swamps/bog
Explanation:
Swamps or bogs are characteristically similar as they both area are known for the poor soil or muddy soil due to the quiet water conditions which is acuumulate by the precipitation mainly. These are have high peat content where mud and decaying or decomposing plant material found.
Bog or swamps are form due to the hundered years of decomposition or decys in plants and plants materials. As it stated that the reptile fossil buriiend lithified among mud and decayed plant material the environment must be bog or swamp.
why is astronomy referred to as observational science and not primarily experimental science
Astronomy is referred to as observational science and not primarily experimental science because it focuses on the acquisition of data from observations of astronomical objects.
When this data are acquired,they undergo analysis and using basic principles of physics.
Unlike experimental Science which seems to build knowledge through directly observing and measuring of objects and phenomenon by scientists.
A good understanding of experimentation is important here.

Answer:
In contrast to normal cells, cancer cells often exhibit much more variability in cell size—some are larger than normal and some are smaller than normal. In addition, cancer cells often have an abnormal shape, both of the cell, and of the nucleus (the “brain” of the cell.) The nucleus appears both larger and darker than normal cells.

How can we justify the conservation of energy using "system/surroundings" terminology for an open, closed, and isolated system?
Answer:
Closed systems do not exchange energy with the environment, while open systems do.
Explanation:
The cause of this is because closed systems are made up of an insulator that surrounds them and isolates them from the environment or adjacent environment.
This insulation prevents heat from being taken in or transferred from the surroundings as in the case of open systems.
How can we justify the conservation of energy using “system/surroundings” terminology for an open, closed, and isolated system?
Answer:
Energy can not be created nor destroyed.
Explanation:
Conservation of energy refers to the statement that energy can't be created nor destroyed, it can only be transformed into another form of energy. For example, if a pendulum swing to and fro motion, the kinetic energy is converted into potential energy. A closed system can exchange energy with its surroundings and transform that energy into heat and work. Total energy of an isolated system remains constant because no energy go out from the system.

Describe how the composition and structure of the atmosphere insulates the planet and protects organism.
Answer: because of its layers
Explanation:
The atmosphere protects life on Earth from incoming ultraviolet (UV) radiation, keeps the planet warm through insulation, and prevents extremes between day and night temperatures.
What is Atmosphere?
An atmosphere is defined as the layer of gas or layers of gases that envelop a planet, and are held in place by the gravity of the planetary body where the planetary atmosphere is present when gravity is great and the temperature of the atmosphere is low.
The Earth's atmosphere extends up to 10,000 kilometers above the surface of the planet, which merges into space.
Beyond the chemical composition which is necessary for life, the composition of the atmosphere in different thermal regions produces weather patterns that in turn determine climate while the upper atmosphere and its ozone layer protect living organisms on Earth from highly harmful UV-B radiation.
Thus, the atmosphere protects life on Earth from incoming ultraviolet (UV) radiation, keeps the planet warm through insulation, and prevents extremes between day and night temperatures.

The amino acid substitution of Val for Glu in Hemoglobin S results in aggregation of the protein because of _____ interactions between molecules. covalent disulfide hydrogen bonding hydrophobic ionic
Answer:
hydrophobic interactions
Explanation:
Hemoglobin S (Hb S) is an abnormal type of hemoglobin where red blood cells become sickle-shaped and these elongated cells have difficulty to pass through small blood vessels. This type of hemoglobin is caused by a substitution (Glu>Val, GAG>GTG) in a β-globin gene variant. When the normal sequence is altered, a different amino acid is synthesized and it modifies the interactions between side chains by hydrophobic interactions, thereby affecting protein folding.

If 35% of the bases in a region of the Drosophila genome are guanine, what percentage in that region are cytosine bases?
Answer:
The correct answer is - 35%.
Explanation:
According to the rule of Chargaff the amount of adneine is equalls to thymine and the amount of guanine is equalls to cytosine in DNA. In a double-stranded DNA Adenine pairs with Thymine and cytosine pairs with Guanine.
So, Percentage of Adenine = percentage of Thymine
and, percentage of Cytosine = percentage of guanine
we know, percentage of guanine = 35%
Thus, percentage of Cytosine will be 35% as well.
