Answer:
Leaching of nutrients occur.
Explanation:
NPK fertilizers are applied to the field all over the world because it has a good effect on the growth and development of plants but it has also some environmental effects such as leaching which pollutes water bodies whereas natural compost is good for the plants as well as for the soil organisms but its breakdown is very slow and it is not readily available to the plants. Lime is also very good for the soil having low pH because lime is basic in nature and it increases the pH of the soil.
Eukaryotic cells are larger than prokaryotic cells.

In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cross an h0m0zygous tall, round pea plant with an h0m0zygous short, wrinkled pea plant. Show the genotypes and phenotypes of the F1 offspring and the probability of each.
__________ Genotype of the h0m0zygous tall, round pea plant
__________ Genotype of the h0m0zygous short, wrinkled pea plant.
Answer:
TtRr - 100%
Explanation:
This question involves two different genes in pea plants. One gene is coding for height and the other for pea shape. The allele for tallness (T) and round (R) pea is dominant over the allele for shortness (t) and wrinkled (r) peas.
According to this question, an h0m0zygous tall, round pea plant (TTRR) is crossed with an h0m0zygous short, wrinkled pea plant (ttrr). The following gametes will be produced by each parent:
TTRR - TR, TR, TR, TR
ttrr - tr, tr, tr, tr
Using these gametes in a punnet square (see attached image), the following proportion of offsprings is produced in the F1 generation: All or 100% TtRr
TtRr will be phenotypically tall and round.

Many Learners Perform Well In Grade 12 But still not accepted into Universities.Explain Two Reasons For This
Answer:
1. Confusion
2. Financial issue
Explanation:
1. The reason I say this is that many of them are not really sure about what they want they want to do in their later future making them a little confused on what to do.
2. It is a common issue which has taken away so many bright minds away from their future in helping the world and their individual community to prosper in different ways.
The reason why many students from grade 12 are not accepted in universities is that they may not be ready to pursue a given career or their parents may not be able to afford it.
Why are grade 12 students not accepted in universities?In the whole of North America, grade 12 is the senior class or the highest class in high school.
Some grade 12 students may not be admitted into university even though they performed well because;
Some of the students who have finished well in grade 12 do not yet have clear cut career orientations.Also, some of them may not have parents that can afford to send them to the university.Hence, a good performance in grade 12 do not guarantee university admission.

1. which of the following organisms is not a strepsirrhines?
Can a gene mutation that does not influence phenotype be considered an adaptation? Why or why not?
Answer:
No; only a small percentage of mutations cause genetic disorders—most have no impact on health or development. For example, some mutations alter a gene's DNA sequence but do not change the function of the protein made by the gene.
Explanation:
Plss help me with this carbon cycle!!!!
Answer:
Plants photosynthesize, so they need, thus absorbs carbon dioxide. Marine plants also need carbon dioxide for photosynthesis so they absorb. Dead plant and animal matter decay to release carbon dioxide as a result.
A carbon footprint refers to the greenhouse gas emissions caused both directly, and indirectly, by an individual, a product, an organization, or an event.

Explore the three different types of ground tissue cells in detail and complete the chart below.
Answer:
parenchyma have primary cell walls (thin) and are unspecialized and metabolically active (photosynthesis, respiration)
collenchyma have primary cell walls (unevenly thick) which provide a level of structural support in areas of high growth, they are alive so have a protoplast
sclerenchyma have secondary cell walls which means they have lignin and are thick, they are functionally dead at maturity so provide support in areas that are done growing and are involved in transport of water

What are your top 3 favorite lifeforms and why? What adaptations help these living things to survive in their environment?
please help
I will give brainliest for the best answer
Answer:
so it's saying what are your favorite animals or plants or living things and how do they survive
hi!! here's ur answer!!
my top 3 favourite lifeforms are- polar bears,tigers and ducks. :D
1) polar bears- are well adapted for survival in the Arctic. Their adaptations include: a white appearance - as camouflage from prey on the snow and ice. thick layers of fat and fur - for insulation against the cold.
2) tigers- striped coat helps them blend in well with the sunlight filtering through the treetops to the jungle floor. The tiger's seamless camouflage to their surroundings is enhanced because the striping also helps break up their body shape, making them difficult to detect for unsuspecting prey.
3) ducks- possess an oily coating that keeps water from settling in their feathers, helping them in staying dry and keeping themselves warm. Their webbed feet, designed like paddles, provide more surface area to push against the water and help them swim.
hope it helps:)

Antibodies are composed of two types of peptides, heavy chains and light chains. One of the major classes of antibody molecules is immunoglobulin G (IgG). Two heavy chains and two light chains form one IgG molecule. Classify each statement as describing the heavy chains, light chains, or both chains of IgG
a. form the antigen-binding site
b. contain multiple variable domains
c. are found in the Fab fragment
d. are found in the FC fragment
e. contain only one constant domain
f. contain multiple constant domains
g. contain only one variable domain
Answer and Explanation:
a. form the antigen-binding site ⇒ both chains
The antigen-binding site is formed by one hypervariable region of the light chain (VL) and one hypervariable region of the heavy chain (VH). So, both type of chains contributes to antigen recognition.
b. contain multiple variable domains ⇒ none
Both chains - light and heavy - contain only one variable domain (VL and VH).
c. are found in the Fab fragment ⇒ both chains
The Fab fragment is composed of portions of both light and heavy chains: each portion contains one variable domain and one constant domain. The Fab fragment binds specifically the antigen.
d. are found in the FC fragment ⇒ heavy chains
The Fc region is composed of portions of heavy chains (CH² and CH³), so it contains constant domains.
e. contain only one constant domain ⇒ light chains
Each light chain contains one variable domain (VL) and one constant domain (CL).
f. contain multiple constant domains ⇒ heavy chains
Each heavy chain contains three constant domains: CH¹, CH² and CH³.
g. contain only one variable domain ⇒ both chains
Both light and heavy chains contain one variable domain. The difference is given by the number of constant domains: light chains have 1 constant domain while heavy chains have 3 constant domains.

Explanation:
The California Mussel ( Mytilus californianus ) is the natural prey of the shore crab ( Carcinus maenas ). Study the graph above. Why would a crab adapt to having larger claws according to the graph?
a. Larger claws would help the crab camouflage in the rocks so the mussels won’t see them.
b. Larger claws would help the crab swim fast in a rough current toward where the mussels are hiding.
c. Larger claws would help the crab crack open the shells of the mussels so the crab can eat them.
d. Larger claws would scare away the mussels with thicker shells causing the crabs to choose a new food source.
Answer:
The correct answer is - c. Larger claws would help the crab crack open the shells of the mussels so the crab can eat them.
Explanation:
The graph (attached) states that the two variables size of claws of the crabs depends on the thickness of the shell of mussels. With the increase in the thickness of the shell of the mussels the size of the claws of crabs also increases and becomes larger.
The most likely explanation of this change would be adapting according to the change in the shell of the crab as they require to crack their shell to eat them as mussels are the primary food source of these crabs.
