Answer:
F1) 1/4 = 25% de la porgenie será AB, IAIB
1/4 = 25% de la progenie será heterocigota para el tipo A, IAi
1/4 = 25% de la progenie será heterocigota para el gruo B, IBi
1/4 = 25% de la progenie será homocigota recesiva, ii
Explanation:
El gen I determina el tipo de sangre de una persona. Es un gen dialelico que muestra alelo dominante I y recesivo I. En personas de tipo A, los alelos son IA dominante, i recesivo.En personas de tipo B, los alelos son IB dominante, i recesivoIA e IB son codomiantes entre si, lo que signofica que hay un tercer fenotypo IAIB, expresando ambos tipos de sangre juntos. El alelo i es recesivo siempre.Genotipo A:
IAIA, Homocigota dominanteIAi, Heterocigotaii homocigota recesivoGenotipo B:
IBIB, Homocigota dominanteIBi, Heterocigotaii homocigota recesivoGenotipo AB:

Make a claim about the types of wastes that the excretory system removes. Support your claim with evidence and explain your reasoning.
Answer:
Explanation:
Urea is the cellular waste product that the kidneys remove from the blood.Kidneys are the two bean shaped organs that has several functions to keep the body healthy. It not only removes urea from the blood, but also helps in the formation of urine and maintaining the fluid level of the body. The two kidneys are placed on the two sides of the spinal cord. The blood enters the kidney through the renal artery. The nephron within the kidneys mainly take out the waste products and the excess water from the blood and purifies it.If the kidneys of a person fail to work properly then it becomes important to perform dialysis for taking out the waste materials from the blood.
What happens to water (H2O) and carbon dioxide (CO2) during photosynthesis?
Answer:
Carbon dioxide turns into glucose and water turns into oxygen
Explanation:
carbon dioxide is combined wih hydrogen atoms in the presence of ATP molecules to form glucose
water molecules split by sunlight energy to form oxygen gas and hydrogen atoms . the oxygen obtained from water is released by the leaf as a by- product

When is energy production the highest?
Answer:
Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.
Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:
Answer:Fossil fuels are the largest sources of energy for electricity generation. Natural gas was the largest source—about 38%—of U.S. electricity generation in 2019.Explanation:The United States uses many different energy sources and technologies to generate electricity. The sources and technologies have changed over time, and some are used more than others. The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.

Natural gas is used in steam turbines and gas turbines to generate electricity.Coal was the second-largest energy source for U.S. electricity generation in 2019—about 23%. Nearly all coal-fired power plants use steam turbines. A few coal-fired power plants convert coal to gas for use in a gas turbine to generate electricity.

Residual fuel oil and petroleum coke are used in steam turbines. Distillate—or diesel—fuel oil is used in diesel-engine generators. Residual fuel oil and distillates can also be burned in gas turbines.
Earthquakes and faults form at __________ boundaries.
transform
convergent
divergent
Answer:
transform
Explanation:
Most earthquakes occur at the boundaries where the plates meet. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones, transform faults, and subduction zones.
In which of the following types of infection will the infected host cell burst?
A lysogenic infection
B prophage infection
C provirus infection
D lytic infection
Answer:
D) lytic infection
Explanation:
During lytic infection, a virus enters the host cell, makes a copy of itself, and causes the cell to burst, or lyse.
Answer:
its D
Explanation:

btw this is 6th grade science and this is not a true or false question
answer:
this is the cell theory, which was proposed by Theodor Schwann in 1839
explanation:
in biology, cell theory is the historic scientific theory it states that living organisms are made up of cells, they are the basic structural/organizational unit of all organisms and all cells come from pre-existing cells.Answer:
This is called cell theory. This was first proposed by Theodor Schwann and became an important part of science today.
what is happening to the amount of carbon in the living things in a biodome
Answer:
Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall. How do they figure it out? They get evidence from the sim and from video of an experiment to determine which organisms do cellular respiration.

If a school is abandoned how will it look like in 10, 50, and 200 years from now?
What animals/plants will it have in every year?
Answer:
Well, I believe that as years go by, plants will start to grow though out the school, things will start to wear out at break down because of not having proper thinks taken care of. Probably some rabbits, mice, basically small animals will start to have homes in the school, no major animals will hang around there because it isn't their habitat.

Urea is formed from that the body does not need.
Answer:
amino acids
anaerobic respiration
aerobic respiration
lungs
liver
kidneys
nitrogen
toxic
Explanation:
Excretion refers to the removal of waste products that is produced from amino acids metabolism.
Carbon dioxide is formed in living organisms in the process of both aerobic respiration and anaerobic respiration and can be removed from the body through lungs.
Urea is produced in the liver and then the blood is to be sent to the kidney and which is excreted from the body.
Urea is compounds of nitrogen which is formed from amino acids that contains toxic substances which the body does not need.
