Answer:
rickettsia and viruses
Explanation:
This is because obligate intracellular parasite are parasite that affect humans and they grow, reproduce and survive inside the host cell. These parasite cannot live or survive outside host cell but they live inside host cell, replicate and they depend on the host cell resources i.e the use host cell resources thereby causing harm on the host cell. rickettsia and viruses are parasite that can only survive inside a living organism.

choose the correct statement about the earth crust A. the earth crust is thin and could be compared to an eggshell B. most of the earth crust is only 6 km deep C. the earth crust is around 200 km deep D. the earth crust is the thickest layer
''A. the earth's crust is thin and could be compared to an eggshell'' is the correct answer.
Why earth's crust is considered an egg shell?The egg is considered a tiny model of the Earth. The thin shell of the egg represents the Earth's crust which is divided into plates. Both earth and egg have a thin and brittle shells. The crust of the earth is broken into various pieces like the cracked shell of a boiled egg. The mantle of the earth is like the egg white part whereas the core of the earth is present in the center like the egg yolk. The earth's crust is broken into pieces that geologists called it plates. The inside of the planet earth is layered like an egg. Scientists considered the surface of the Earth to be cracked like a big eggshell. They call these pieces tectonic plates that cover the Earth. The plates float slowly on the surface and sometimes crash with each other, and move away from each other.
So we can conclude that option A is the right answer about the earth's crust.

What is the end result of DNA replication?
O An mRNA strand that will be used to create a protein.
O two strands of DNA that are identical to cach other
O An MRNA strand that will not be used to create a proteir
O Two strands of DNA that are different from one another.
Answer:
two strands of DNA that are identical to each other
Explanation:
Replication is defined as the process in which two identical copies of DNA is formed from parent DNA strand. The end result of DNA replication is two strands of DNA that are identical to each other which are called chromatids. The process of DNA replication is known as semi-conservative as the end result is consist of one new and one old chain of nucleotides.
Hence, the correct answer is "two strands of DNA that are identical to each other".

According to the kinetic theory of matter, how many particles that make up a substance are constantly in motion?
Answer:
D
Explanation:
According to the kinetic theory of matter, option D. all the particles that make up a substance are constantly in motion.
The Kinetic Theory of Matter states that all matter is made of particles that are atoms and molecules that are constantly in motion in the substance, therefore, particles of all matter have kinetic energy.
Some particles have more kinetic energy than other particles due to fact that all particles of matter do not move at the same speed even though particles of matter are constantly moving.The temperature of matter or object is the average kinetic energy of the particles in an object.Thus, the correct answer is - option D. all the particles.

Which statement best describes the Law of Superposition?
Answer:
B) In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.
Explanation:
CORRECT
The best statement for law of Superposition is in undisturbed layers of sedimentary rock, the lowest layers contain the older rocks. Thus option B is correct.
What is law of superposition?Law of superposition stated that a key stratigraphic concept indicating that within a sequence of sedimentary rock layers, the oldest layer is at the bottom and the layers are increasingly younger with ascending order in the sequence.
Superposition is defined as the ability of a quantum system to exist in numerous states until it is measured.
It can also be stated that an assumption that serves as a foundation for the sciences of geology, archaeology, and other fields concerned with geological stratigraphy.
Thus, the best statement for law of Superposition is in undisturbed layers of sedimentary rock, the lowest layers contain the older rocks. Thus option B is correct.

Which of the following is typical of aerobic respiration?
decreases a plant’s weight
contains two stages, glycolysis and fermentation
produces methane as a byproduct
produces little energy
Answer:
decreases a plant’s weight
Explanation:
Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.
Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.
Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.
Hence, the correct answer is "decreases a plant’s weight".
Why are green plants considered producers?
Green plants directly absorb sunlight to make energy.
Green plants contain chlorophyll.
Decomposers consume green plants.
Green plants are eaten by secondary consumers.
Answer:
The organisms that are capable of preparing their own food from simple inorganic substances like carbon dioxide and water by using sunlight energy in the presence of chlorophyll are called producers. The green plants synthesize their own food through the process of photosynthesis and thus are called the producers.plants produce food for themselves, they are known as producers.When a person doesn't get enough sleep, their immune system:

What factor prevents us from finding fossils from the Precambrian era?
A. Life-forms in this era had no skeletons.
B. This was before life existed on Earth.
C. Life was destroyed by a series of mass extinctions.
D. There are no rocks left from that era.
Answer:
rhe answer is that the rocks of that time are buried deeply under the soil.
The factor that prevents us from finding fossils from the Precambrian era is that life-forms in this era had no skeletons. Therefore, option (A) is correct.
What was Precambrian era?The Precambrian era spans from the formation of Earth about 4.6 billion years ago to the start of the Cambrian period about 541 million years ago. During this time, life on Earth consisted mainly of simple, single-celled organisms such as bacteria and algae.
These organisms lacked the hard shells, bones, and other structures that are typically preserved as fossils. Therefore, the fossil record from the Precambrian era is relatively sparse, consisting mainly of impressions and other traces left by these early organisms in sedimentary rocks.

Give two examples of phospholipid soluble molecules? How can these molecules move across the cell membrane? What affects the direction of their movement
Answer:
1. Only small uncharged molecules can diffuse freely through phospholipid bilayers (Figure 2.49). Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. 2. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm). 3. Objects change their motion because unbalanced forces act on them. There are four main factors that affect the motion of objects. These factors are force, friction, inertia, and momentum.
Explanation:
Hope this helps. ^_^
Answer:
Examples include steroids and Vitamins
Phospholipids ,as the name implies fall under the category of lipids. Phospholipids have a hydrophilic "head" which has a strong attraction to water molecules.The hydrophilic head contains a phosphate group which allows for reactivity with water molecules.
Phospholipids also contains two hydrophobic "tails" which has a strong repulsion to water. The tails are derived from fatty acids and are joined by a glycerol molecule. These compounds are less reactive to water molecules .
These properties make phospholipids to be soluble in both water and oil which favors the movement of molecules such as Steroids and Vitamins in and out of the cells through the process called Diffusion.
The direction of movement depends on the concentration of molecules as they usually move from a region of high concentration to a region of lower concentration to ensure there is equilibrium and proper functioning of cells.
