Endothermic animals, like humans, are warm blooded and make heat on their own. Ectothermic animals, like reptiles, are cold blooded and must find warmth in their environment. If a lizard must go to warm areas around them to get heat, what type is it ? Endothermic or Ectothermic
Answer:
Lizards are ectothermic.
Explanation:
Lizards are apart of the reptile class and are cold-blooded. Which means their bodies do not generate stable internal temperatures and they have to rely on their surroundings to keep warm.

Describe what will happen when a red blood cell is placed in:
- hypotonic solution
- hypertonic solution
- isotonic solution
In your description you must write about:
- water movement
- what will happen to the cell.
Answer:
Describe what will happen when a red blood cell is placed in:
Hypotonic Solution ⇒ The red cell would burst due to the influx of water. The water would have moved out of the cell which cause it to shrink. Red blood cells don't have the cell wall and contractile vacuoles and as well as it would not be able to maintain their shape leading to their rupture.
Hypertonic solution ⇒ A cell loses its H2O molecules when it is placed in hypertonic solution. Hypertonic solution is the one which contain more concentration of solutes as compared to the concentration of solutes in cytoplasm of cell. Which means that a solution contains less water as compared to the water within the cell.
Isotonic solution ⇒ When a red blood cell is placed in an isotonic solution, there will be no movement of water. Both the concentration of solute and water are equal both intracellularly and extracellularly

In India, rainwater harvesting is a centuries-old practice that has recently received renewed attention. By intercepting and collecting rainwater where it falls, rainwater harvesting has been extensively used to directly recharge groundwater at rates exceeding natural recharge conditions. As seen in the photograph, rainwater harvesting pools have been built in India, with the capacity to hold 5 million liters of rainwater a day. The costs of this approach are relatively modest, and individual and community programs can locally develop and manage the required infrastructure. Required:
This type of rainwater harvesting in India most closely ensures the continual use of which table?
Answer:
I would guess the water table. There is no visible photograph.
Explanation:
The water table would remain relatively consistent with seasonal changes of rainfall patterns. It can be used to determine rainfall rates over years or even decades.
This type of rainwater harvesting in India most closely ensures the continual use of water table.
What is water table?The line between the saturated and unsaturated zones of the earth's crust is the water table. Groundwater fills any voids between rocks and sediments below the water table.
The water table is an underground line separating the soil's surface from the region where groundwater seeps into rock crevices and voids between sediments. At this limit, the water pressure and atmospheric pressure are equal.
The unsaturated zone is the portion of the soil surface above the water table where water and oxygen coexist in the gaps between the sediments. Because there is oxygen in the soil, the unsaturated zone is also known as the zone of aeration.
Therefore, This type of rainwater harvesting in India most closely ensures the continual use of water table.

Which are characteristics of bryophytes? (Select all that apply.)
Most of them need water to help reproduce.
Most of them grow tall.
Most of them live in shady, moist, or humid areas.
Most of them are vascular plants.
Answer:
most of them are vascular plants
most of them grow tall
Explanation:
The characteristics of bryophytes are:
Most of them need water to help reproduce.
Most of them live in shady, moist, or humid areas.
What are bryophytes ?Bryophytes are a group of non-vascular plants that include mosses, liverworts, and hornworts. They are small, simple plants that lack true roots, stems, and leaves. As non-vascular plants, they do not have a system of tubes or vessels for transporting water and nutrients, and thus they rely on diffusion and osmosis for these functions.
Due to their lack of vascular tissue, bryophytes cannot grow tall like vascular plants. Instead, they tend to form low, carpet-like mats on the ground or on other surfaces.
Because they require water for reproduction, they are commonly found in moist, shady areas where they can absorb water directly from the environment.
Bryophytes play an important ecological role in their environments, serving as habitat for a variety of small organisms, contributing to nutrient cycling, and helping to prevent soil erosion. Despite their small size and lack of vascular tissue, they are a diverse and widespread group of plants that have adapted to a variety of different habitats around the world.
Another adaptation of bryophytes is their ability to store water in specialized cells called hydroids, which can help to prevent dehydration in dry conditions. Some species of bryophytes also have structures called gemmae, which are small, multicellular reproductive structures that can detach from the parent plant and grow into new individuals under favorable conditions.

In the garden pea, several different genes affect pod characteristics. A gene affecting pod color (green is dominant to yellow) is approximately 7 mu away from a gene affecting pod width (wide is dominant to narrow). Both genes are located on chromosome 5. A third gene, located on chromosome 4, affects pod length (long is dominant to short). A true-breeding wild-type plant (green, wide, long pods) was crossed to a plant with yellow, narrow, short pods. The F1offspring were then testcrossed to plants with yellow, narrow, short pods. If the testcross produced 800 offspring, what are the expected numbers of the eight possible phenotypic combinations
Answer:
Green/Wide/Long, G-W-L- = 186 individuals Yellow/narrow/ long, gg ww L- = 186 individuals Green/wide/ short, G-W-ll = 186 individuals Yellow/narrow/ short, gg ww ll = 186 individuals Green/narrow/ long, G-wwL- = 14 individuals Yellow/wide/ long, gg W-L- = 14 individuals Green/narrow/short, G-wwll = 14 individuals Yellow/wide/ short, ggW- ll = 14 individualsExplanation:
Available data:
• One gene affecting pod color (green is dominant to yellow)
• One gene affecting pod width (wide is dominant to narrow)
• Both genes are located on chromosome 5 and approximately 7 mu away from each other.
• A third gene, located on chromosome 4, affects pod length (long is dominant to short).
• Cross: A true-breeding wild-type plant (green, wide, long pods) was crossed to a plant with yellow, narrow, short pods.
• The F1offspring were then test-crossed to plants with yellow, narrow, short pods.
• The testcross produced 800 offspring.

To calculate the numbers of the F2 generation, we first need to calculate the frequencies of recombination and parental of the linked genes. We know that they are 7MU apart from each other. The map unit is the distance between a pair of genes for which every 100 meiotic products one results in a recombinant one.
MU = 7 means that there is 7% of recombination for genes that express color and width. This is:
MU = 7 = 7% recombination
We have two possibilities of recombination: green/narrow and yellow/wide. Each of these recombinants has half of the possibilities of occurring, so:
7 map units = 7 % of recombination in total
= % Gw + % gW
= 3.5 % + 3.5 %
Gw = 3.5% = 0.035
gW = 7%/2 = 0.035
For the parentals, we can calculate
100% - 7% = 93% of parental in total
= % of GW + % gw
= 46.5% + 46.5%
GW = 46.5% = 0.465
Gw = 46.5% = 0.465
The length gene is located in a different chromosome so it assorts independently. This is, of the gametes will be long, L, and the other 50% will be short, l.
L = 50% = 0.5
L = 50% = 0.5
Now we need to figure out how to relate these frequencies. All we need to do is to multiply the frequencies of occurrence obtained previously for linked and independent genes, for each possible phenotype. This is:
Green/Wide, GW = 0.465 Yellow/narrow, gw = 0.465 Green/Narrow, Gw = 0.035 Yellow/Wide, gW = 0.035 Long, L = 0.5 Short, l = 0.5Phenotypic frequencies:
Green/Wide/Long, G-W-L- = GW x L = 0.465 x 0.5 = 0. 2325 Yellow/narrow/ long, gg ww L- = gw x L = 0.465 x 0.5 = 0. 2325 Green/wide/ short, G-W-ll = 0.465 x 0.5 = 0. 2325 Yellow/narrow/ short, gg ww ll = 0.465 x 0.5 = 0. 2325 Green/narrow/ long, G-wwL- = 0.035 x 0.5 = 0.0175 Yellow/wide/ long, gg W-L- = 0.035 x 0.5 = 0.0175 Green/narrow/short, G-wwll = 0.035 x 0.5 = 0.0175 Yellow/wide/ short, ggW- ll= 0.035 x 0.5 = 0.0175Finally, as we need to obtain the numbers of the individuals with those phenotypes, we need to multiply each frequency by N, which is the total number of individuals in the F2 (N = 800).
Green/Wide/Long, G-W-L- = 0. 2325 x 800 = 186 individuals Yellow/narrow/ long, gg ww L- = 0. 2325 x 800 = 186 individuals Green/wide/ short, G-W-ll = 0. 2325 x 800 = 186 individuals Yellow/narrow/ short, gg ww ll = 0. 2325 x 800 = 186 individuals Green/narrow/ long, G-wwL- = 0.0175 x 800 = 14 individuals Yellow/wide/ long, gg W-L- = 0.0175 x 800 = 14 individuals Green/narrow/short, G-wwll = 0.0175 x 800 = 14 individuals Yellow/wide/ short, ggW- ll = 0.0175 x 800 = 14 individuals
