Answer:
The correct answer is -
1) 9/16
2) 1/16
Explanation:
The probability of an offspring in F2 generation that exhibits dominant traits for both characteristics (green pod and tall pod shape) is 9/16.
The probability of one dominant and one recessive trait (either greed pod color and short OR yellow pod and tall) is 3/16.
The probability of recessive traits for both characteristics showing in the phenotype (yellow color and short) is 1/16. This gives as a 9:3:3:1 ratio for the phenotypes (phenotypic ratio).
The correct answer is -
1) 9/16
2) 1/16

HEY UJALA CAN U PLEASE HELP ME IN THIS QUESTION HOW HORMONES ARE INVOLVED IN OSMOREGULATION OF KIDNEYS
Answer:
Hormones are involved in the osmoregulation of kidneys by regulating the levels of water.
Such as if the water level is excess in the body fluids, the hormone will help the kidneys to filter as much water as they can from the glomerular capillaries. So, As a result dilute urine is formed.
Now, If the water level is very low in the body fluids, the hormone will help the kidneys to absorb most water and filter less water from the glomerular capillaries. As a result the urine formed is concentrated.
In Chapter 3, "Coordination and Control" You will come to know that the hormone is ADH (Anti-diuretic hormone) called vasopressin.
Answer:
Kidney plays a very important role in Osmoregulation by regulating the amount of water reabsorbed.Anti Diuretic harmone produced by pituitary gland plays a key role.Kidney regulate osmotic pressure of a mammals blood through extensive filtration and purification in a process known as osmoregulation.
The loop of Henle establishes a salt gradient in the medulla, anti diuretic harmine regulates the level of water reabsorption in the collecting duct.
Harmones like ADH helps in reabsorption of water.

Which viral replication cycle is represented in part A of this diagram?
O A. Dormant cycle
OB. Replication cycle
C. Lysogenic cycle
O D. Lytic cycle
Answer:
The correct answer is - option D. lytic cycle.
Explanation:
The lytic cycle is one of the two viral reproduction cycle. Generally, it is the major reproduction cycle. In this cycle reproduction of the viruses takes place inside the host cell and produce more viruses. In the production of the more viruses the host cell and it''s destruction takes place in the end. The 5 steps that takes place are as follows:
1- attachment - viruses attach to the cell.
2-penetration- only nucleic acid or genetic material is injected into the host cell through the hole made by the tail fibers and enzymes.
3- synthesis - replication of viral nucleic acid and protein and envelope.
4- assembly - assembling of the new viruses formed.
5- release.

Why does the troposphere contain the most water vapor out of the atmosphere? Everywhere says that it does but why?
Answer:
The troposphere does contain the most water vapor out of the atmosphere
Explanation:
The troposphere does contain the most water vapor out of the atmosphere because the troposphere is where all the weather conditions like: rain cloudy, hurricanes take place and all the weather conditions have water vapor because most of the weather conditions have clouds, or water vapor.
Because plants release water during the transpiration process, the troposphere contains the most water vapour in the atmosphere. This remains here, and as a result rain forms.
What is the atmosphere?
The atmosphere is the earth's outer layer, which is further subdivided into troposphere, stratosphere, mesosphere, and so on. The troposphere is the part of the atmosphere closest to the earth, and it is where rain and clouds form.
The upper stratosphere is less disturbed and more stable than the troposphere, as less wind disturbance is seen here. In this layer, planes and jets are travelling. It has a special layer called the "ozone layer" that protects the earth from the UV light of the sun. The mesosphere is the coolest of these atmosphere layers.
The troposphere has disturbances such as those caused by winds; clouds form here. There are various gases, such as oxygen, carbon dioxide, nitrogen, water vapor, and so on. The water vapour is the result of transpiration from plants and evaporation from water bodies.
Hence, this troposphere layer contains water, because the water above it cannot remain liquid due to the increased temperature of the stratosphere.

All materials within ecosystems can be recycled.
Answer:
All the things expect enegry are recycled.
Explanation:
When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled. The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.But incase of enegry it cannot be recycled but frequently transfered from one form to another form.

_____ are surface appendages that allow a bacterium to stick to a surface. _____ are surface appendages that allow a bacterium to stick to a surface. Fimbriae Mitochondria Ribosomes Cell walls Flagella
Answer:
Fimbriae
Explanation:
Fimbriae are hollow, hairlike structures made of protein, which allow bacteria to attach to other cells.
Fimbriae are surface appendages that allow a bacterium to stick to a surface. The correct option is a.
What are Fimbriae?At the surface of bacterial cells are long filamentous polymeric protein structures called fimbriae. They make it possible for the bacteria to attach to particular receptor structures and colonize particular surfaces.
They are 3–10 nanometer thick hair-like extensions that surround bacteria and number 1,000 on average. When compared to flagella, they are smaller. Although pilli and fimbriae are frequently used interchangeably, pilli are longer. Both gram-positive and gram-negative bacteria contain them.
As a result, they are so tiny that an electron microscope is required to see them. The fimbriae's adhesin molecules play a key role in the adhesiveness of the structures.
Therefore, the correct option is a. Fimbriae.

Crop rotation is a method of soil conservation because _______. a. the land produces more than one type of crop b. it requires plowing and tilling that reduces soil compaction c. it does not use the same parcel of land in sequential seasons d. it avoids the depletion of soil nutrients
Answer:
d. It avoids the depletion of soil nutrients.
Explanation:
Crop rotation is the process of planting different crops in the same area of land in rotation. This allows the breathing of the soil as well as the retention of nutrients in the soil.
Crop rotation is one form of conserving soil as it helps in saving the nutrients of the soil from getting depleted. As different crops require different nutrients, the change in crop plantation between different types of crops help in maintaining the fertility of the land. This way, when crops are planted in rotation, there is also the rotation of the different nutrients required for the different crops planted, thus allowing the cycle of nutrient change to take place.
Thus, the correct answer is option d.
