Answer:
Earth's primordial soup
Explanation:
Alexander Oparin was a Soviet biochemist who proposed theories for the origin of life through a book he called "The Origin of Life". He claimed that life on earth came about as a result of a gradual chemical evolution which is a mixture of carbon-based molecules that he called Earth's primordial soup (or sometimes called "organic soup").

Suggest why a cell within the trunk of a tree cannot carry out photosynthesis.
Answer:
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. Note that root cells do not contain chloroplasts, as they are normally in the dark and cannot carry out photosynthesis.
Explanation:
The trunk of a tree consists of dead tissues and serves only to support the weight of the tree crown. This portion of the tree does not contain chloroplast, hence photosynthesis is not carried.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The part of the trunk region of the tree does not have chloroplast, chlorophyll pigments, and other required machinery which is significantly utilized by the leaves of the tree in order to perform photosynthesis. Due to this, the trunk part of the trees is not capable to carry out the same process.
Therefore, the most prominent reason why a cell within the trunk of a tree cannot carry out photosynthesis is well described above.

In the outer layer of the sun, energy is transported outward by the rising of hot plasma and sinking of cooler plasma. This transfer is known as
Answer: Convection.
Explanation:
We have 3 types of heat transmission.
Radiation: Heat is transported as electromagnetic waves, this is not the case shown here.
Conduction: When we have two objects with different temperatures and we put them in contact, the system will want to go to equilibrium (both objects have the same temperature) so the hot object will give heat to the cooler object. We usually see this with solid objects.
Convection: It is the heat transfer due to the bulk movement of the molecules, so this need a material medium (it can not take place in solids, because the position of the molecules is fixed in the solids).
Then the rising of hot plasma and sinking of cooler plasma is convection.
Which is a correct statement?
Select one:
a. As porosity increases, permeability stays the same
b. As porosity increases, so does permeability
c. As porosity increases, permeability decreases
d. Porosity and permeability are unrelated
help pls!!!
As porosity increases, permeability decreases It increases as particle length increases. via definition, permeability is a measure with which fluids will go with the flow though a porous rock, soil or sediment. a material that has high porosity does not have to have high permeability.
Smaller particles have a low permeability. this is due to the fact there's less space among debris, which reasons a lower porosity, which makes water travel slower through the ground. Smaller debris have a higher capillarity.
Porosity is the amount of pore area that is between particles in soil or rocks. Permeability takes this pore space and connects the voids collectively so that water can pass thru. Porosity is extra associated with garage of water, whilst permeability is extra related to groundwater motion and flow.
To calculate the permeability of a porous material, use Darcy's law equation: Multiply together the fluid discharge fee, dynamic viscosity, and distance traveled. Divide the end result from step one with the aid of the move-sectional place of the fabric elevated with the aid of the strain difference on either aspect of the material.

what are thylakoids? I will give BRAINLIEST!!
Answer:
each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana.
Thylakoids are membrane-bound compartments inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana.
Explanation:
Answer:
They are membrane-bound compartments inside chloroplasts (the food producers of the cell) and cyanobacteria (group of photosynthetic bacteria).

Which organisms synthesize carbohydrates, and in which cell organelle(s) does this synthesis occur?
a. animals in mitochondria
b. plants in mitochondria
c. plants in chloroplasts
d. animals and plants in mitochondria
e. animals and plants at ribosomes
Answer:
C
Explanation:
Green Plants are the main producers of starch as carbohydrate.In order to carry out this special organelle Chloroplast are specially adapted for this purpose,
Green plant are made up of Chlorophyll which are the green pigments that for trapping sunlight for the synthesis of starch to occur.
Photosynthesis is the process of synthesis of the starch.It involves the reaction of C02 with water in the presence of sunlight and enzymes to give oxygen as the byproduct, and Starch( carbohydrate) as the main product.
This process occur in two pathways the light dependent pathways and the light independent pathways,
Green plant and some organisms phytoplankons,algea are capable of producing starch through photosynthesis because of the green pigment they possess.Therefore they are said to be Autothrophic.

Answer:
b A moveable moveable joint joint that that allows allows back back and and forth forth movementmovement
Explanation:
A moveable joint that allows back and forth movement. Therefore, the correct option is B.
What is moveable joint?A synovial joint, commonly referred to as a movable joint, allows for a variety of motion between bones. Limbs and other areas of the body that require movement have movable joints.
These joints have a synovial membrane that secretes synovial fluid, and they are enclosed in a capsule of connective tissue. This fluid helps lubricate the joint and lower friction as the bones move in closer proximity to each other.
Ball-and-socket joints, pivot joints, saddle joints and gliding joints are some examples of movable joints. Different types and ranges of motion are possible with each type of joint.
