Team of scientists is studying several plant species that they think could become new farm crops. The scientists want to apply selective breeding to develop one of the species into useful crop plants. Which property of a plant species would be MOST USEFUL for meeting the scientists' goal? A. very low genetic variation B. very high genetic variation C. producing only a few fruits and seeds each growing season
Answers
Answer:
B. very high genetic variation
Explanation:
Selective breeding is the process by which crops or animals with desired phenotypic traits are chosen to produce offspring, which will contain the desired qualities. In this case, a group of scientists is trying to apply the principles of selective breeding to develop a particular crop plant.
This goal of producing a useful crop plant by the scientists can only be achieved when the plant species in question possess a HIGH GENETIC VARIATION i.e. difference in genetic constitution of individuals of the same species. This allows the individuals in the population to survive better.

explain how temperature affects population size
Answers
Answer: High temperature and drying were both associated with greater per capita mortality rate. Smaller population sizes at high temperatures and drying regimes may result from increased desiccation of adults and thus higher mortality. These precipitation effects on adult production are absent at 22°C

Other than toxic metals, temperature rise and low resource availability are factors that are also known to stress populations. A rise in temperature generally accelerates metabolic rates and hence population growth rate

In humans, brown eyes (B) is dominant over blue eyes (b). Teddy has brown eyes, his mother has brown eyes and his father has blue eyes. Their punnett square is represented in the picture attached:
Teddy says that all 4 children in his family have brown eyes. Is this possible?
Question 12 options:
a. Yes, because every child has a 50% chance of having brown eyes
b. No, they should be half brown eyes and half blue eyes
c. No, at least one of his siblings should have brown eyes
Answers
Answer:
A. Yes, because every child has a 50% chance of having brown eyes
Explanation:
This is the correct answer
According to the Punnett square that is given below, the argument made by Teddy may not have correct evidence. This is because it is not possible to have all 4 children in his family has brown eyes. So, the correct option for this question is B.
What is Punnett square?A Punnett square may be characterized as a type of table in which all of the plausible consequences for a genetic cross between two individuals with known genotypes are given.
According to the context of this question, the genotype of the mother is Bb which has a brown phenotype because brown eye (B) is dominant over blue eyes (b). While the genotype of the father is bb. This is blue eyes.
When both these genotypes are crossed, the genotypes of offspring are Bb, Bb, bb, and bb. This means that the individuals have both traits of blue and brown phenotypes by 50% each.
Therefore, the correct option for this question is B.

Phillip Gingrich finds an S-shaped bone in this partial skull, a sigmoid process, which is unique to
one particular order of animals in the water today... which one?
Answers
Answer:
A primitive whale which he named Pakicetus.
Explanation:
Philip Gingrich is a vertebrate paleontologist at the University of Michigan. He has performed extensive research on whales at the Egyptian desert of Wadi Hitan. His research team member discovered a skull whose braincase was bigger than that of a walnut. Gingerich was able to link the small-brained animal, to an early whale.
The auditory bulla had an s-shaped bony crest known as the sigmoid process and these two features helped whales to hear in water. The case, however lacked other features that helped whales hear beneath the waves. This led Gingrich to the conclusion that the unknown animal was semi-aquatic. This finding also lent credence to the possibility of whales evolving from terrestrial animals.

D
Explanation:
I think so
1. Coriolis effect would deflect the path of the air mass to the west.
2. A horizon would provide the best assessment of the fertility of a soil.
3. Label E is located above Label D.
4. A La Niña can be described as cooler than usual waters in the tropical Pacific
The correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
The Coriolis effect is the deflection of moving air (or an object) due to the Earth's rotation. The air moving in the northern hemisphere is deflected to the right of its intended path due to the Coriolis effect. As a result, in the Northern Hemisphere, air masses traveling from high to low latitudes will be deflected west.
The A horizon, commonly known as the topsoil, contains the most organic matter and nutrients, making it the most fertile layer of soil. This is the layer in which organic components such as degraded plant matter and humus interact with mineral particles to provide an optimal environment for plant growth.
The location at latitude D, which lies above the equator and parallel to the top of the Hadley cell, is where you might expect to find the driest average conditions in the Hadley cell circulation pattern mentioned in the question (north of the equator). Due to the compression, the air in the Hadley cell becomes warm and dry as it descends, resulting in arid or desert-like conditions.
La Niña is a climate phenomenon that causes cooling of sea surface temperatures in the central and eastern tropical Pacific Ocean. It represents the inversion phase of the El Niño–Southern Oscillation (ENSO) cycle.
Therefore, the correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
