Answer:
Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

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.

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 flies, Red eyes are dominant to white. If a true-breeding red-eye fly bred with a true breeding white-eye fly, the offspring will be:
Answer and Explanation:
Available data:
Red eyes are dominant to whiteDominant allele RRecessive allele rCross: true-breeding red-eye fly bred with a true breeding white-eye fly
Parentals) RR x rr
Phenotypes) Red-eyed White-eyed
Gametes) R R r r
Punnett square) R R
r Rr Rr
r Rr Rr
F1) 4/4 = 100% of the progeny will be heterozygous for the trait expressing red eyes, Rr
---------------------------------------------------------------------------------------------------------
In Drosophila melanogaster, the fruit fly, the gene for the eye color is X-linked. So in this species:
- X⁺ expresses red eyes ----- > + is the dominant allele for red color
- X⁻ expresses white eyes ----> - is the recessive allele for white color
Option 1: true-breeding red-eyed females and white-eyed male
Parentals) X⁺ X⁺ x X⁻Y
Phenotypes) Red-eyed female White-eyed male
Gametes) X⁺ X⁺ X⁻ Y
Punnett square) X⁺ X⁺
X⁻ X⁺X⁻ X⁺X⁻
Y X⁺Y X⁺Y
F1) 4/4 = 100% of the progeny will express red eyes
50% of individuals are red-eyed males, X⁺Y
50% of individuals are red-eyed heterozygous females, X⁺X⁻
Option 2: true-breeding white-eyed females and red-eyed male
Parentals) X⁻ X⁻ x X⁺Y
Phenotypes) Red-eyed female White-eyed male
Gametes) X⁻ X⁻ X⁺ Y
Punnett square) X⁻ X⁻
X⁺ X⁺X⁻ X⁺X⁻
Y X⁻Y X⁻Y
F1) 2/4 = 50% of the progeny will be females expressing red eyes, X⁺X⁻
2/4 = 50% of the progeny will be white-eyed males, X⁻Y

how does sickle cell anemia mutation impact the structure and function of the protein produced
Answer:
The beta globin protein is one of the subunits of hemoglobin, a protein necessary for the oxygen-carrying function of red blood cells. People with the sickle cell mutation in both copies of the HBB gene produce proteins that clump together and lead to changes in the shape and behavior of red blood cells.

Which of the following diagram(s) accurately depict high turgor pressure in a plant?
Answer:
I believe it's B
Explanation:
The diagram that accurately depicts high turgor pressure in a plant is diagram B. The correct option is B.
What is the turgor pressure?The pressure that pulls the plasma membrane up against the cell wall is known as turgor pressure. It is also known as hydrostatic pressure and is known as the pressure in a fluid when it is at equilibrium and is measured at a specific spot within the fluid.
Therefore, the turgor pressure helps the plant's cells elongate, and the cells also employ this phenomenon to control transpiration by opening and closing the stomach.
Water is held in vacuoles, which are organelles in plant and fungus cells that are surrounded by a single membrane.
The turgor of a living cell is influenced by three primary factors:
An adequate supply of water.The formation of osmotic substances.A semi-permeable membrane.Therefore, the correct option is B, diagram B.

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.
