Which of the following characteristics is true of dicot plants?
netted pattern of leaf veins
two cotyledons in seed
vascular bundles arranged in a circle
All of these choices are correct.
Dicot plants are the plants having two cotyledons as the name suggest. In these plants, the veins of the leaf have a net-like appearance, forming a pattern known as reticulate venation, and the vascular bundles arranged in a circle, i.e., option D, all choices are correct.
What are the examples of dicot plants?Most dicot plants are common garden plants, shrubs and trees, and broad-leafed flowering plants such as magnolias, roses, and geraniums.
These typically also have flower parts which are based on a plan of four or five or multiples with some exceptions.
They have net leaves vein pattern, two cotyledons, and ring shaped vascular bundles.
Thus, the correct option is D.

How did the first small organic molecules form in earth’s earliest atmosphere? There are two main theories discussed. Make sure you know both. Refer to Miller and Urey experiment and meteorite theory
zapped gas/liquid into amino acids
many amino acids thought to have come from meteorites
a mixture of gases and water that Miller thought were present on early Earth was heated and zapped with electricity to mimic lightning. This created five identifiable amino acids
newscientistcom
We know amino acids exist in some kinds of meteorites and interplanetary dust
Many left-handed amino acids were found inside the Murchison meteorite. Most were kinds not found on Earth.
92 different amino acids have been identified in the Murchison meteorite. Of these, only 19 are also found on Earth. The remaining amino acids have no apparent terrestrial source. This discovery led scientists to consider the possibility that Earth's life forms originated elsewhere in the universe. And the same cosmic process that may have helped life arise on Earth could also be seeding life elsewhere in the universe

Although both humans and bacteria have ribosomes, streptomycin—which blocks ribosome function—does not harm a human who ingests it. Why?.
Streptomycin does not harm a human who ingests it because bacteria have different ribosomal units.
What is a ribosome?Ribosomes are organelles used by cells to synthesize proteins, it is for that reason that they are called protein factories.
Ribosomal units are different in eukaryotic cells (e.g. human cells) compared to prokaryotic cells and they do not bind to streptomycin in eukaryotes.
In conclusion, Streptomycin does not harm a human who ingests it because bacteria have different ribosomal units.

The question is as follows,
A marine ecosystem is represented below (you will find the image in the attached files).
- Decomposers
6) Top carnivore: sharks, dolphins, albatross
5) Third-level carnivores: squid
4) Second-level carnivores: larger fish
3) First-level carnivores: juvenile stages of fish, jellyfish, crustaceans, and sea stars
2) Herbivore: zooplankton and cockles
1) Primary producers: phytoplankton and seaweed
- Sun provides energy to producers
What is lost to the environment at each of the trophic levels of this ecosystem?
In a trophic web, 10% of a link's energy is transferred to the following link, and the other 90% dissipates to the environment as heat. The answer is heat.
What is the trophic web?The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.
The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
The first link corresponds to a producer organism -autotroph-.The following links are the consumers -heter0trophs-: herbivores and carnivores.The last links are the decomposers that degrade organic matter from dead organisms.Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.
Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
What is the 10% rule?From the energy that reaches the Earth's surface, only 0.1 or 1% is absorbed by autotroph organisms.
This small percentage of energy flows through all organisms in the ecosystem -from autotrophs to heter0trophs- until it dissipates in the environment.
Only 10% of energy is transferred from one level to the next one. The remaining 90% is dissipated as heat to the environment. This assessment is called The 10% rule.
This rule states that only about 10% of the energy stored as biomass at one trophic level, ends up as biomass at the next trophic level.
The progressive reduction of energy determines the number of trophic levels (4 or 5).
Heat is lost to the environment at each of the trophic levels of this ecosystem.

Explanation:
Tree squirrels can have different fur colors.
Squirrels live in forests where foxes also live. Foxes hunt squirrels for food. Squirrels that have fur the same color as the trees are harder for the foxes to see and catch.
[IMAGE ONE]
The diagram above shows a population of squirrels that lived in a forest. Scientists had previously only seen brown and gray squirrels in this forest; they had never seen squirrels of any other color.
The diagram below shows how the population changed after many generations.
[IMAGE TWO]
How did the color of the trees in the squirrels’ environment change? Explain what happened to the squirrels over many generations.
Answer:
The gray squirrels were easy to see and catch so they died quickly and the population dwindled. The brown squirrels were probably almost the same color as the tree so they were harder to see and catch. The remaining gray squirrels ended up having no other options than to mate with brown squirrels, which probably made appear black squirrels and since the black squirrels population raised, means they are harder to see and be caught by foxes.
How the trees became more black too? I have no idea, sorry.

What is the effect of climate change on polar regions?Climate change causes melting of ice caps in colder regions where polar bears live. This change has made it harder for polar bears to successfully hunt seals. This situation will lead to extinction of polar bears in this location because they can't get their food which leads to their death.
