Answer:
1) By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.
3) By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.
4) Like natural selection, genetic engineering may be used on all organisms, including humans.
Explanation: In natural selection there is overtime selection for one particular trait and is mostly based on phenotype, whilst genetic engineering uses genotype of an organism and it is the deliberate modification of an organism by manipulating the genetic material
Answer:
The correct answer is: B. The amount of air in a room never changes.
Explanation:
- A system is said to be in equilibrium when the net components in the system remains constant (no increase or decrease) with time.
- The air in a room never remains constant and always undergoes dynamic movement into and out of the room. At equilibrium, the net air in the room remains constant as amount of air exiting the room is balanced by the amount of air entering it.
- Evaporation of water in the form of water vapour from a cup into the atmosphere is not in a state of equilibrium as the amount of water evaporating from the cup is not replaced in the cup so there is a net decrease in water level in the cup.
- The decrease in nitrogen percentage in a room is not in equilibrium as the nitrogen concentration of the room is not constant.
- A blade of grass growing taller is not in equilibrium as a constant height of the grasses is not maintained.
Answer:
Cell X
Explanation:
Prokaryotes do not have a nucleus, this is because a nucleus is a membrane-bound organelle. Prokaryotes do not have any membrane-bound organelles (including chloroplasts), however, they do have a cell membrane, as this is the site of diffusion and other types of transport.
Answer:
También se ha debatido el hábitat de la abiogénesis. Si bien alguna evidencia sugiere que la vida puede haberse originado a partir de la no vida en los respiraderos hidrotermales en el fondo del océano, es posible que la abiogénesis ocurriera en otros lugares, como en las profundidades de la superficie de la Tierra, donde las protoceldas recién surgidas podrían haber subsistido con metano o hidrógeno, o incluso en el océano. costas, donde los proteinoides pueden haber surgido de la reacción de los aminoácidos con el calor y luego entrar al agua como gotitas de proteína parecidas a células.
Answer:
The correct answer is Aldosterone
Explanation:
Aldosterone is a steroid hormone that is secreted from the adrenal cortex.Aldosterone helps in the excretion of potassium ions from our body.
That means if potassium sparing diuretics increase urination witout loss of potassium ion from our body then these diuretics will have to work against receptor foe aldosterone.
