You are studying leaf development in a member of the mustard family. You identify several mutants of interest in this plant and
monitta

Answer:

•The relationship between the twist and the wild type flower in the first crossing is known as a COMPLETE DOMINANCE

•The relationship between the forked and the wild type flower in the second crossing is also known as a COMPLETE DOMINANCE

•The relationship between the pale and the wild type flower in the third crossing is known as an INCOMPLETE DOMINANCE

Explanation:

A complete dominance is characterised by having one of the genes (the dominant gene) in an heterozygous condition, completely masking the effect of the other (the recessive gene) of thesame allelic pair. E.g. if the genes in allelic is represented with Aa, "A" is said to completely dominate "a" if it does not allow "a" to Express itself phenotypically.

The heterozygous condition is always the result of the F1 generation

and the F2 generation of a Complete dominance is always characterised by a phenotypic ratio of 3:1 which is in line with the results gotten from the first crossing and the second crossing as stated in the question.

An complete dominance is characterised by having an intermediate progeny in the F1 generation which was evident in the result of the third crossing. Also a phenotypic ratio of 1:2:1 in the F2 generation is also a characteristic feature of an Incomplete dominance relationship which was also evident in the third crossing.

write a paragraph describing the impact Carbon on our global temperatures include the terms carbon sink carbon Source ocean acid
kozerog [31]

Answer:

Global warming is caused by the greenhouse effect caused  by greenhouse gases, such as carbon dioxide, in the earth's lower atmosphere. A release of carbon dioxide into the atmosphere by carbon sources such as fossil fuel burning increases the greenhouse effect hence increased global warming. Another effect of higher carbon dioxide levels in the atmosphere is oceans acidification.  The oceans will absorb more carbon dioxide and form more carbon acid hence lowering the pH of the waters. To alleviate this phenomenon, carbon sinks need to be protected such as forest because they sequester carbon dioxide from the atmosphere and store it as carbohydrates in their biomass.

sineoko [7]

Last Friday after dealing with the stressors of daily life, Jane was likely to have <u>increased level of cortisol</u> in her blood stream.

Explanation:

Daily life activities, responsibilities, duties, events all leads to a lot of stress among individuals. This stress affects our body, thoughts, mind, feelings and behavior.  

Cortisol is a stress hormone secreted by the adrenal glands by the triggering of adenocorticotropic hormone of the pituitary gland.

Stressors due to daily life activities and other health problems leads to cortisol awakening response and increases the level of cortisol in the blood stream in order to cope up with the increased stress.

Increased cortisol levels causes a number of health issues like anxiety, depression, headache, digestive issues, cardiac problems, sleep disturbance, cognitive impairment etc

Eric places some room-temperature strawberries into his freezer. Which of the following correctly describes what happens to the
Arisa [49]

Answer:

The heat from the strawberries transfers to the freezer and causes the strawberries to freeze.

Explanation:

When Eric-palces some room temperature strawberries into the freezer, he is changing the temeprature of the strawberries. When the strawberries are in the room tempertaure, they are absorbing certain amount of heat.

When they are placed in the freezer they are releasing the heat to the environment and this leads to condition called as phase change. Due to this phenomenon, the heat from the strawberries transfers to the freezer and causes the strawberries to freeze.
