Explain the differences between the structures of wind and insect pollinated plants and adjust the mark scheme.
Answers
Answer:
Unlike the typical insect-pollinated flowers, flowers adapted to pollination by wind do not produce nectar or scent. In wind-pollinated species, the microsporangia hang out of the flower, and, as the wind blows, the lightweight pollen is carried with it.

Answers
Answer:
20% adenine, 20% thymine, 30% guanine, 30% cytosine
Explanation:
Edwin Chargaff stated in his rule that, in a DNA molecule, the amount of purine bases (Adenine and Guanine) should equate the amount of pyrimidine bases (Cytosine and Thymine). Mathematically, this means that;
A + G + C + T = 100%
Where;
% Adenine base = % Thymine base
% Guanine base = % Cytosine base
Hence, according to this question, the DNA molecule described will contain
20% adenine = 20% thymine,
30% guanine = 30% cytosine
20% A + 20% T + 30% G + 30% C = 100%

The surface area/volume ratio is an important factor for one celled organisms. As a cell's volume grows, its surface area/volume ratio ______________, making it more difficult to acquire enough nutrients via diffusion. Question 7 options: increases freezes decreases stays the same
Answers
Answer: decreases
Explanation:
The surface area to the volume ratio will decrease as the volume of the cell increases or the cell gets larger. Therefore, if the volume of the cell increases beyond the certain limit the cell will not be able to imbibe nutrients as not enough material can pass through the cell membrane to accommodate the increase in volume of the cell.

Alyssa is observing two cells, X and Y. Each cell is from either a plant or an animal. She records some of her observations in a chart.
Cell Observations
Cell X Cell Y
has lysosomes lacks lysosomes
lacks a cell wall has endoplasmic reticulum
has ribosomes has a nucleus
Which additional observation will Alyssa most likely make?
Cell X has a cell membrane, and Cell Y does not.
Cell Y has a cell membrane, and Cell X does not.
Cell Y has a larger vacuole than Cell X.
Cell X has a larger vacuole than C
Answers
Answer:
Cell Y has a larger vacuole than cell X
Explanation:
Cell Y is the plant cell, only plant cells have a tough and rigid cell wall, animal cells do not. The observation that Cell X lacks a cell wall as well as having lysosomes is indication that Cell X is an animal cell. The answer that Cell Y has a larger vacuole is true because plant cells need to store more water and nutrients than animal cells and will have a much larger vacuole.

how has limiting factors for the ecosystem impacted pythons in the everglades
Answers
Answer:
Explanation:
Non-native Burmese pythons have established a breeding population in South Florida and are one of the most concerning invasive species in Everglades National Park. Pythons compete with native wildlife for food, which includes mammals, birds, and other reptiles. Severe mammal declines in Everglades National Park have been linked to Burmese pythons.
The most severe declines in native species have occurred in the remote southernmost regions of Everglades National Park, where pythons have been established the longest. In a 2012 study, populations of raccoons had dropped 99.3 percent, opossums 98.9 percent, and bobcats 87.5 percent since 1997. Marsh rabbits, cottontail rabbits, and foxes effectively disappeared.
The mammals that have declined most significantly have been regularly found in the stomachs of Burmese Pythons removed from Everglades National Park and elsewhere in Florida. Raccoons and opossums often forage for food near the water’s edge, which is a habitat frequented by pythons in search of prey.
