Gregor Mendel crosses a true-breeding tall plants (TT) with a true-breeding short plant (tt). What are the predicted phenotypes for the offspring ?
a. all tall
b. all short
c. ratio of 1 tall : 1 short
d. ratio of 3 tall : 1 short
Answer:
a. all tall:
Explanation:
Tall plants (TT) are the more dominate trait. Use the Pundett square (I will try to recreate it as best as possible but it will not look good):
t t
T Tt Tt
T Tt Tt
As you can (kind of) tell, T appears on all offsprings, and as the dominate trait, it will take over 100% of the time.
The next generation (depending on who you are breeding them with), will have a different result.

Biodiversity
Genetic engineering
Bioremediation
Hemodialysis
NEED HELP ASAP PLEASE
Answer:
Option B, Genetic engineering
Explanation:
Biodiversity determines the different types of species living in a given area. Hence it is incorrect
Bioremediation is basically a waste management system in which organisms are used to break down hazardous substances into less toxic substances. Hence, it is also incorrect
Hemodialysis is used to remove or filter out wastes and water from blood. Hence, it is also incorrect
Genetic engineering is used to produce organism with desired trait by altering their DNA and hence the associated Phenotype. Thus, it is the correct answer
Hence, option B is correct
Answer:
Genetic engineering
Explanation:
Genetic engineering is a technique in which DNA of desired gene is isolated from the body of an organism and inserted into the body of host cell. The host cell then develop organism or species with the characteristics of desired gene. The organism with genetic manipulation are called genetically modified organism (GMO).
Genetic engineering has many application such as human growth hormones, mass-produce insulin, follistim (for treating infertility), monoclonal antibodies, increasing productivity of animals and plants et-cetra.
Some animals are unable to breed or produces organism due to genetic diosrders or mutaions, with the help of genetic engineering a DNA with gene of interest can be inserted in the host or animal cell, which will treat or remove the natural barries and will make enable it for breeding.
Hence, the correct answer is Genetic engineering.
Arctic ice retreat is threatening many species in this ecosystem. Their resources are being cut and they are needing to find new ways to survive. Do you think in your lifetime you will see drastic effects to the species in this ecosystem and why? Will that affect other ecosystems?
Answer:
no
Explanation:because they will find new ways to survive in the environment
Answer:
We are already seeing drastic effects to the ecosystem and it's wide assortment of species. Animals such as polar bears, and seals are losing their breeding and hunting grounds. Polar bears in particular are losing their ways to catch seals for food and interbreeding with grizzly bears. Fish and whales from warmer parts of the world are starting to move up north and are becoming invasive. Most importantly, since cold water from the melting ice are mixing with ocean currents, global climates and weather systems are changing course. Ultimately, in about 500 years, there could be a large Global Climatic Shift that may put us into another Ice Age.

Which statement about fossils could be used as evidence that
evolution by natural selection has been in effect for millions of
years?
Fossils found in higher layers of rock are older than those
found in lower layers.
Fossils found in lower layers of rock are more complex than
those found in higher layers.
© Fossils of current species have been found throughout rock
layers that are billions of years old.
0 Fossils of species that no longer exist but are ancestors of
current species have been found in rock layers.
Fossils of species that no longer exist but are ancestors of current species have been found in rock layers. Thus, the correct option is D.
What are Fossil fuels?A fossil fuel is a hydrocarbon-containing material which is formed naturally in the Earth's crust from the remains of dead organisms such as plants and animals which are extracted and burned as a fuel. The main fossil fuels which are present in the earth's crust include coal, oil, and natural gas.
The evolution of species is easily confirmed by the presence of fossils of the most diverse species of the living beings in the world. This is because, fossils are the records of species which do not currently exist, however there are existed millions of years ago and are similar to the current species, being their ancestors.
Therefore, the correct option is D.

Answer:
The metabolic rates of aquatic organisms increase as the water temperature increases. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive. Pure water only has a pH of 7.0 at 25 degrees Celsius. This process occurs seasonally in holomictic (mixing) lakes, as the water temperature

Why we should be concerned about the increase in amount of the green house gases in the atmosphere?
Answer:
We should be concerned about the amount of green house gases released into the atmosphere because the more gases are released, the more they accumulate in the atmosphere and trap heat, which contributes to global warming, which is causing massive changes in our environment all around the world.

A student in genetics class is studying the inheritance patterns in fruit flies. He is looking at the traits for wing length, long versus short, and colorbrown versus gray. Using a dihybrid cross of two flies that were heterozygous for long wings and brown color. Long wings and Gray are dominant. How many offspring will have long wings and brown color?
Answer:
LLgg, Llgg , two out of 16
Explanation:
Given,
Dominant - Long wings and Gray color
Recessive - Short wings and Brown color
Let the allele for long wings be "L" and the allele for short wings be "l".
Let the allele for brown color be "g" and allele for gray color be "G"
Genotype of parents
LlGg
Gametes of the parent
LG, Lg, lG, lg
Dihybrid cross is between LlGg and LlGg
The offspring produces will be as follows -
LG Lg lG lg
LG LLGG LLGg LlGG LlGg
Lg LLGg LLgg LlGg Llgg
lG LlGG LlGg llGG llGg

Answer:
Sure grass. And there is a lot of grass. Compete with wild horses, wild pigs, wild goats, wild "golfer's who are way off the fairway. Wild deer are in the forests, wild goats in the hills so buffalo and horses manage the plains and the back nine. So much grass there was no competition...with the wild rabbits.
