A gardener crosses tall true–breeding pea plants with short true–breeding ones. Tall plants are dominant to short ones. He collects the seeds to grow F1 plants and then allows them to self–pollinate to form an F2 generation. Which of the following describes the traits of the offspring correctly?
A.
Three–fourths of the F1 and one–half of the F2 plants will be tall.
B.
All of the F1 and three–fourths of the F2 plants will be tall.
C.
Three–fourths of the F1 and all of the F2 plants will be tall.
Answers
Answer:
Explanation:
Let T = tall allele (dominant), t = short allele
True breeds are homo-zygous.
So the gardener is crossing TT with tt, with the resulting genotype of F1 all equal to Tt, i.e. all Tall hetero-zygous.
When the F1 pea plants are allowed to self-polinate, F2 results in Tt crossing with Tt, with the genotypes TT, Tt, tT and tt, and phenotypes 75% tall and 25% short, tall being dominant.

What usually accompanies a cold spell in Minnesota?
O A. The polar jet stream moves south.
O B. The polar jet stream moves north.
O C. The horse latitudes moves north.
O D. The doldrums moves south.
Answers
The polar jet stream moves south is accompanies a cold spell in Minnesota. Therefore, option (A) is correct.
What do you mean by polar jet stream?Polar jet stream is a belt of strong upper-level breezes that sits on the polar front. The winds generally move in a westerly direction in midlatitudes and are strongest at the tropopause, the upper boundary of the troposphere.
The convergence of cold air masses coming down from the Arctic and warm air coming up from the tropics creates the jet. Profound box and soak edges arise as the denser virus air sinks and redirects warm air locales north, giving the fly stream its wavy appearance.
The northern polar jet stream is the most important jet stream for aviation and weather forecasting on Earth because it is much stronger and lower in altitude than the subtropical jet streams.

How does reducing gene flow cause speciation?
A. it increases fossilization
B. it creates patches of favorable habit
C. it increases gene flow
D. it allows populations to become genetically different
Answers
Gene flow cause speciation because it allows populations to become genetically different.
What is speciation?Speciation is the process of creating a new plant or animal species. When a group within a species separates from other members of the species and develops its own distinct feature known as speciation.what is gene flow?Gene flow refers to the movement of alleles (genes) from one population to another across geographical boundaries. Gene flow is the movement of genes into and out of a population.Individual creatures may migrate to new populations and reproduce, or gametes may move .for example as a consequence of pollen transfer among plants.How does gene flow affect speciation?By recombining the gene pools of the groups and thereby mending the emerging differences in genetic variation that would have led to full speciation.
The establishment of daughter species, gene flow strongly opposes speciation.
Hence, the correct option is D

Garlic mustard has been introduced to the beetles ecosystem. Describe what would happen to the beetles population as a result and explain why.
Answers
Answer:
It would collapse
Explanation:
Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plant
In addition, invertebrates and other consumers that rely on these natural plant species for food are harmed by the spread of this invasive "weed". Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plan
Garlic mustard is an invasive plant species that is known to negatively impact native plant populations in ecosystems.
What is invasive plant?An invasive plant is a non-native plant species that is introduced to an ecosystem and has the ability to spread and negatively impact native plant and animal populations.
Garlic mustard is known to release chemicals that inhibit the growth of other plant species, including some that the beetles may rely on for food.
This could lead to a reduction in food availability for the beetles, which may cause a decline in their population.
Additionally, if the beetles are not adapted to feeding on garlic mustard, they may not be able to digest or utilize the plant efficiently, leading to further declines in population.
Thus, the impact of garlic mustard on the beetle population will depend on the specific beetle species and the extent to which they rely on native plant species for food.

Answer: Plants can use the energy from sunlight to turn water and carbon dioxide into. When the cell has enough organelles to make two cells, the division process starts. Let's discuss the process of photosynthesis again, this time taking a closer look at it. Just A long rope to represent the cell wall.
Jump rope is thin and elastic which is made by twisting two threads together which somewhat looks like a cell membrane can be used as a model for plant cell membrane.

Answers
Answer:
In the presence of lidocaine, the action potential was NOT affected at R1 because lidocaine was applied downstream of R1
Explanation:
Lidocaine is an anesthetic that has the power to neutralize neuromal membranes. This anesthetic power allows the ionic fluxes capable of stimulating impulses to be diffused and this allows a dormancy to be achieved. However, when lidocaine is applied downstream to a molecule or structure, the action potential of that structure or molecule is not affected and it may continue to receive impulses.
