Answer:
Venus and Mercury are the only planets in our solar system that do not have moons. Venus and Mercury have a gravitational pull that is weaker than the gravitational pull of the Sun, so they wouldn't be able to hold onto their own moon.

Which of these best represents an ecosystem?
A. herd of deer grazing in a field
B. Mushrooms decomposing organic matter
C. A pitcher plant growing in nutrient-poor soil
D. Frogs and fish swimming in a pond in the forest
Answer:
d
Explanation:
ecosystem is more than one animal
The best answer that best represents an ecosystem is D. Frogs and fish swimming in a pond in the forest. An ecosystem is a complex network of living and non-living components that interact with each other in a particular environment.
What is the role of each organism ?Each organism in an ecosystem has a role to play and is dependent on the other organisms and the environment for its survival. In the case of D. Frogs and fish swimming in a pond in the forest, the living components are the frogs and the fish. The non-living components are the pond, the forest, and the atmosphere.
The frogs and the fish rely on the pond for food and shelter, and the pond relies on the surrounding forest and atmosphere for nutrients and energy.
The frogs and fish also interact with each other, as the fish feed on the frogs and the frogs feed on the insects that live in the pond. All of these components are connected and interact with each other, making this a perfect example of an ecosystem.

What happens if a horse gains or lose a chromosome? Explain why mutations and chromosomal changes occur. ANSWER ASAP <3
Answer: Gaining or losing a chromosome will result in major genetic changes for that horse, as either it will be missing important DNA or will have too much DNA. Either can cause mutations to occur in the animal's genome. Chromosomal changes are caused by an error during either meiotic or mitotic cell division. An error could be that a cell has too much copies of a chromosome, or not enough, which causes the mutations mentioned above. Hope this helps some, I know it's not a super meaty answer.

1. How do bacteria differ, and what is happening to the bacteria when they are exposed to antibiotics in their environment? Write a full paragraph for more.... Will give brainliest
Answer:
Bacteria have the ability to develop resistance by using enoded instructions by their DNA. Generally, the resistance genes present within plasmids. In this mechanism, they are able to share their DNA and make other bacteria resistant too.
This mechanism takes place by avoiding the expression or effectiveness of antiboitics designed to kill or prevent these strains. The strains that are able to survive, share their DNA with others and increase their numbers.

In the given scenario, image B represent the relative directions of plate movement at this type of plate boundary. The correct option is B.
What is plate boundary?A plate boundary is a three-dimensional surface or zone where the velocity (speed or direction) of one lithospheric plate in relation to the next lithospheric plate changes significantly.
Divergent, convergent, and transformal plate borders are where the majority of seismic activity takes place. Sometimes the plates get hooked when they pass each other, creating pressure.
At the margin of the lithospheric plates, plate boundaries can be classified as convergent, divergent, or conservative.
Image B depicts the relative directions of plate movement at this particular type of plate boundary in the scenario.
Thus, the correct option is B.

1.suggest a function of xylem cells
2.suggest a function or the phloem cells
3.suggest a function for the stomata
4.suggest a function for the guard cells
Answer:
1.
Explanation:
Xylem cell is a plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.
2. Phloem is the vascular tissue in charge of the transport and distribution of organic nutrients. The phloem is also a pathway to signaling molecules and has a structural function in the plant body.
3. Stomata are composed of a pair of specialized epidermal cells referred to as guard cells. Stomata regulate gas exchange between the plant and environment and control water loss by changing the size of the stomatal pore.
4. Guard cells optimize leaf gas exchange in response to changing environmental conditions and their turgor is controlled by alterations in atmospheric CO2 concentration, light intensity, humidity, and the drought hormone abscisic acid.
x + x =24 find the value of x
Answer:
x = 12
Explanation:
2x= 24
2x/2=24/2
x=12
Confirmation:
12 + 12 =24 (Correct)
We have to,
Solve for the value of x,
→ x + x = 24
→ 2x = 24
→ x = 24/2
→ [ x = 12 ]
Hence, the value of x is 12.
Which of the following is not a similarity between prokaryotic and eukaryotic cells?
-They both contain genetic material
-They both contain a plasma membrane
-They both contain cytoplasm
-They both contain membrane bound organelles
Answer:
"They both contain membrane bound organelles" is the answer.
Explanation:
The statement that prokaryotic and eukaryotic cells both contain membrane bound organelles is not a similarity between them.
WHAT ARE PROKARYOTES AND EUKARYOTES:
Prokaryotic cells are cells that possess membrane-bound organelles including a nucleus while eukaryotic cells are cells that do not possess membrane-bound organelles. The membrane bound organelles include endoplasmic reticulum, nucleus, golgi apparatus etc. Prokaryotic and eukaryotic cells are similar in the sense that they both possess the following:They both contain genetic material e.g DNA, RNA.They both contain a plasma or cell membraneThey both contain a cytoplasm.However, they do not both possess membrane-bound organelles. Prokaryotic cells like bacteria etc lack them.

Which part of the stem transports sugars?
O Phloem
O Xylem
O Cortex
O Cambium
Answer:
Phloem
Explanation:
Phloem transports sugars and amino acids dissolved in water.
The part of the stem that transports sugars is the phloem. Therefore, option A is correct.
The phloem, a vascular tissue, transports glucose from the leaves to various regions of the plant. It and xylem are the stem's major vascular tissues. Sieve elements connect to produce lengthy sieve tubes in the phloem. Sugars and other organic compounds flow through this stem network of sieve tubes and partner cells.
Translocation moves phloem sugars. Pressure flow loads carbohydrates into the phloem from the source (usually leaves) and moves them down the tubes by osmotic pressure gradients to the sink (plant regions that need sugars for development or storage).
The stem's vascular tissue, the phloem, transfers glucose and other organic molecules from the leaves to other sections of the plant, enabling plant development and metabolism. Therefore, option A is correct.
