Answer:
Nitrogen
Explanation:
All living organisms need nitrogen in order to build proteins and build DNA.
Some animals (most) get nitrogen by eating plants I believe.
Which is the complementary dna strand to the following: aattcgtaccg
Answer:
The sequence along one strand is the "complement" of the sequence along the other strand, so that when two strands are bonded each base is paired with its complementary partner. A-T-T-C-G-G-A-C-T-A, is paired with this complementary strand: This allows A and T to pair and C and G to pair. Each base hydrogen-bonds to its complementary base.

Termites share an endosymbiotic relationship with the protozoan that live in their gut. Which statements are true of this relationship? Check all that apply.
A: The termite benefits from the relationship by receiving food from the protozoan.
B: The protozoan benefits from the relationship by receiving shelter and food from the termite.
C: Protozoan only exist inside termites.
Answer:
Explanation:
The true statements are:
-The termite benefits from the relationship by receiving food from the protozoan
-The protozoan benefits from the relationship by receiving shelter and food from the termite
The second statement is obvious. The protozoan lives in the termite, eating what the termite eats and enjoying the shelter the termite provides. The first statement is also true, but poorly worded. the termite does not actually receive food from the protozoan. The protozoan only helps to digest the food that the termite has already consumed.

Explanation:
When we say that DNA replication is semiconservative, we mean that: None of the other answer options is correct. only half of an organism's DNA is replicated during each cell division. parental DNA stays in the parent cell and daughter DNA ends up in the daughter cell. when DNA is replicated each new double helix contains one parental strand and one newly synthesized daughter strand.
Answer:
each new double helix contains one parental strand and one newly synthesized daughter strand, is the correct answer
Birds are uniquely classified from other organisms because they all(1 point) eat seeds. eat seeds. have feathers. have feathers. lay eggs. lay eggs. have wings.
According to the research, birds are uniquely classified from other organisms because they all have feathers.
What are birds?It is an oviparous and vertebrate animal whose body is protected by plumage and which has a pair of wings generally suitable for flight.
Feathers are characteristics of the bird class thanks to these they can camouflage, regulate body temperature and identify and differentiate themselves from other groups of animals since they may have wings, beaks and legs, but none have feathers.
Therefore, we can conclude that according to the context, birds are uniquely classified from other organisms because they all have feathers.

there are 3 ways that thermal energy can be transferred below write a paragraph describing each one with an example
Answer:
Thermal energy can be transferred by conduction, convection or radiation
Explanation:
Thermal energy is the energy that flows from one point to another due to temperature differences between the points. There are three ways by which thermal energy is transferred which are conduction, convection and radiation.
In conduction, thermal energy is transferred in solids usually metals due to their good heat conductivity. An example is seen in the use of metals for preparing meals. Heat (or thermal energy) is transferred from the fire to the metal to the food.
Convection occurs in fluids (liquids and gases). It usually occurs in a cyclic manner. For example in heating water, thermal energy is gained by water molecules closest to the heat source (at the base of the container) and become lighter causing them to rise to the top. The molecules at the top become denser and sink to the bottom whereby they gain energy and rise in a similar manner. This repeated phenomenon occurs in a cyclic form whereby there's displacement of colder and denser molecules by warmer and lighter molecules. Another example is the occurrence of sea and land breezes.
Radiation occurs without the need of any material medium unlike conduction and convection. In radiation, heat is directly transferred from one point to the other without being transferred by molecules. This is seen in how thermal energy from the sun reaches the earth. In other words, heat is transferred in a vacuum

Structures of the Excretory System Cells produce wastes such as salts, carbon dioxide, and ammonia. For homeostasis to be maintained, these wastes need to be removed from the body. Excretion is the process by which metabolic wastes are elimiNted from the body.
- The skin excretes excess water, salts, and a small amount of urea in sweat.
- The lungs excrete carbon dioxide and water vapor.
- The liver converts potentially dangerous nitrogen wastes to urea.
- The kidneys are the major organs of excretion. They remove excess water, urea, and metabolic wastes from the blood. Ureters carry urine from the kidneys to the uriNry bladder, where it is stored until it leaves the body through the urethra.
1. Why does the body need an excretory system?
Answer:
okay lets go.
Explanation:
A body needs an excretory system because:
Withouts the excretory system the wastes such as sweats ,urea will be continously collects in the body and they are harmful therefore can cause death.
