Assuming that eye color follows mendellian inheritance, two heterozygous parents would breed as follows:
Ee x Ee
Punnett sqaure
E e
E EE Ee
e Ee ee
All organisms possessing allele E will express dominant phenotype.
From two fruit flies, 75% would have the dominant phenotype.
What do you mean by phenotype?The phenotype is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes.
Phenotype refers to an individual's observable traits, such as height, eye color and blood type. A person's phenotype is determined by both their genomic makeup (genotype) and environmental factors.
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

moves upward.
A metal rod would not be a good choice for roasting marshmallows because
metal transfers thermal energy.
Answer:
O As the air around the campfire is heated and becomes less dense, it rises and moves upward.
Explanation:
This is true because, the convection transfer needs the particle of elements to transport the heat from where it is in abundance to where it is in less abundance. Just like a water boiling becoming hot at the point closer to the fire than the top of the pot, so also will the air around campfire transfer heated air from the place closer to the campfire to upwards aware from the fire.
Convection is the flow of air around the campfire when it is heated and the decrease in density as it rises upward in the atmosphere. Thus, the correct option is C.
What is convection of heat?Convection is the transfer of heat from one place to the other due to the movement of fluids present in it. It is a distinct method of heat transfer in systems. The convective heat transfer involves combined processes of conduction and advection in a system and its surrounding. Convection is the dominant form of heat transfer in liquids and gases.
The thermal radiation in the fire is mostly in the form of infrared waves and visible light. However, the campfire heat transferred via convection shoots straight up in the sky and never reaches to the ground level.
Therefore, the correct option is C.

Calculate the rate of photosynthesis (mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 3 mm from the initial level in 20 min, and when measuring cellular respiration it took 15 minutes for the water level to move down 1 mm.
Answer:
The rate of photosynthesis is 13 mm/hr
Explanation:
The rate of net photosynthesis is given by;
rate of net photosynthesis = 3 mm / 20 min = 1.5 mm/ 10 min
The rate of cellular respiration is given by;
rate of cellular respiration = 1 mm / 15 min = 0.667 mm / 10 min
The rate of photosynthesis is given by;
rate of photosynthesis = rate of net photosynthesis + rate of cellular respiration
rate of photosynthesis = 1.5 mm/ 10 min + 0.667 mm / 10 min
rate of photosynthesis =2.167 mm/ 10 min
[tex]rate \ of \ photosynthesis \ in \ mm/hr = \frac{2.167 \ mm}{10 \ min} *\frac{60 \ min}{1 \ hr} = 13 \ mm/hr[/tex]
Therefore, the rate of photosynthesis is 13 mm/hr

Explain how wildfires help restore soil nutrients to forest ecosystems.
Answer:
Wildfire help restore soil nutrients - Wildfire kills off the soil organisms that consume soil nutrients. Wildfires restore soil nutrients by decreasing the amount of underbrush in forests that contribute to nutrient loss. Wildfires break down organic material faster than decomposition, thus renewing soil nutrients more quickly.
Explanation:
Wildfire help restore soil nutrients by eliminating soil organisms that consume soil nutrients and decomposition of materials that help to renew soil nutrients.
What is soil nutrients?
Soil nutrients are essential ingredients needed by plants for growth, they include nitrogen (N), phosphorus (P) and potassium (K).

What is asexual reproduction?Asexual reproduction is defined as the process of reproduction in which only a single parent is involved. Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.

How are humans affected by population growth of other organisms in anarea?
Answer:
yes
Explanation:
other organisms include things such as plants, insects and animals which can play a large role in the population. For example, if you have a sudden rise in the population of misquitoes that can be really bad since they can spread diseases to people when they are sucking blood. Antoher example is if there is a sudden growth of animals that eats a certain crop, then farmers will stuggle to maintain their crops and the list goes on. Hope this helps :)
One of the favorites to win a marathon to be held at sea level has been invited by a sponsor to train in Bolivia (very high altitude place) for three weeks before the race. The sponsor has promised to fly him to the race a day before the race. Based on your understanding of hemoglobin function, would you advice the athlete to accept the invitation or continue with his/her plans to train at low altitude
Answer: At high altitude the body will get prepared for marathon.
Explanation:
The human body is able to adapt the high altitude by long-term and immediate acclimatization. At high altitude the lack of oxygen is sensed at the carotid arteries. It causes the increase in rate of breathing or hyperpnea.
In addition at high altitude the heart beats faster, gradually the body will also compensate itself for low availability of oxygen and get prepared for marathon.

The correct answer is -
wetlands - land and water
estuaries - freshwater and salt water
Explanation:
There are three types of aquatic ecosystems that are lentic, lotic, and wetlands. Lentic ecosystems include slow-moving or non-moving water systems like pools, lakes, or ponds. The Lotic system on the other hand is aquatic systems with faster-moving water systems like the ocean or river also known as estuaries.
Wetlands are the system that has unique properties of having vegetation adapted according to the condition or situations on the water in saturated soil flood with water seasonally or permanent.

How do you know if something is alive? Describe some of the characteristics of living things.
Answer:
We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:
Reproduction - to make more of the same organism
Sensitivity - the ability to detect and react to stimuli
Nutrition - eat and digest food.
Movement - the ability to change its position or location
Respire - to breathe / gas exchange
Excretion - get rid of toxic / materials in excess
All living things show the characteristics above.
For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.
Answer:
To be alive organisms have to include all of the following:
- Made up of a cell or cells
- Has DNA
- Can reproduce
- Responds to the environment
- Grows and develops
- Exchanges energy
- Evolves
Explanation:
Prokaryotic and Eukaryotic cells are both alive because they contain all of the seven necessary characteristics listed above. Viruses are not alive because they do not contain all of the seven characteristics listed above.
