Answer:
hi, this is the answer
These phenotypic differences are inherited from mother cells to daughter cells.
The process of differentiation involves the expression of particular genes for each cell type in response to cues from neighbouring cells and from the extracellular environment, and the suppression of others.

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.

Which of the following depicts correct base-pairing in DNA?
A-G-A
B-A-U
C-C-T
D-T-A
Answer:
D. T- A
Explanation:
In dsDNA the bases in the two strands are paired through hydrogen bonds forming base pairs (bp). Adenine forms two H-bonds with thymine from opposite strand and vice-versa. Similarly, guanine is bonded with cytosine with three H-bonds. As a result, always a purine comes opposite to a pyrimidine.

A new type of fish has been discovered. It has vibration receptors on its snout and virtually nonexistent eyes. Based on these characteristics, in which part of the ocean is this fish most likely found?
If a fish has vibration receptors on its snout and virtually nonexistent eyes, these characteristics are found in the fish which leaves at the bottom of the ocean.
What is the use of receptors on fish?It is found under the skin, the lateral line made of sensory receptors known as neuromasts. While the cilia in the neuromasts vibrate, the fish can sense.
The lateral line may likewise feel and observe water pressure (depth), currents, objects, prey, and predator movements, this senses increase the chance for the survival of the fish.
Food and lure that is living and moving would be simple for fish to detect as it has a smell, sound and vibration.
Therefore, with vibration receptors, at the bottom of the ocean, this kind of fish generally found.

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
lg LlGg Llgg llGg llgg
Offspring with long wings and brown color – LLgg, Llgg , two out of 16
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.

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.

Healthy marine ecosystems are important for society since they provide services including food security, feed for livestock , raw materials for medicines, building materials from coral rock and sand, and natural defenses against hazards such as coastal erosion and inundation.
How does it effect humans:
Recreation, tourism and water transport are familiar services provided by many marine ecosystems. Some unique estuarine, coastal, and marine habitats are also important stores of genetic material and have educational and scientific research value as well.
