Which curve would most likely represent the behavior of the receptor once it has been activated by its signal molecule?

________ spend almost all of their time on the ground instead of in trees.

muminat

This question isn't very specified but i'm pretty sure by the context the answer is gonna be tree frogs.

¿Que dos moléculas necesitan las plantas para la fotosíntesis?

viktelen [127]

Para realizar la fotosíntesis las plantas necesitan varios elementos que se encuentran en el medio ambiente.

Energía luminosa: impacta sobre las hojas y es absorbida por el pigmento fotosensible de la planta, la clorofila.
Agua: La fotosíntesis requiere un suministro constante de agua. Ésta llega a las hojas a través de las raíces y tallos.
Clorofila: Pigmento de color verde contenido en el cloroplasto. Se encarga de la absorción de la luz, para llevar a cabo la fotosíntesis.
Dióxido de carbono: Es absorbido por unos minúsculos poros, llamados estomas, en la parte inferior de la hoja.
Oxígeno: subproducto de la fotosíntesis. Sale de las hojas hacia el exterior a través de lasestomas.

A student was asked to compare a cell to a typical home. In this analogy, the cell mitochondria are like the (floor,furnace,or r

sdas [7]

Answer:

um...

If A Plant Cell Were A House...

Cytoplasm

Vacuole

The Cytoplasm

would be the carpeting. The Cytoplasm is the goo that all the organelles reside in, and all the furniture and stuff in the house kind of sit there in the carpeting.

The vacuole would

be the closets and pantries. The vacuole holds random things that the cell needs, and closets and pantries can hold anything you feel like putting in them, like food or clothes.

Lysosome

Mitochondrion

The mitochondrion would be the kitchen. It produces energy for the cell to use, and the kitchen produces food, energy for humans.

Nucleus

Endoplasmic Reticulum

Rough

The nucleus would be my mom. The nucleus controls the cell, and my mom controls my house.

Ribosomes

The Smooth ER would be just plain hallways. The ER is a vast network of tubing that things the cell needs travel down.

The Rough ER would be hallways filled with cattle. This wouldn't be a very good example, because it isn't a very vast network. A lot of people travel down them, though! The Rough ER is like smooth, except with ribosomes.

If you had a herd of cattle in your yard, it would be them. If not, just the kitchen, like the Mitochondrion. Ribosomes synthesize proteins, and cattle make milk, which is full of protein. Also, in the kitchen you can make proteins with different types of dairy, like cheese or milk.

Smooth

Lysosome

Golgi (apparatus)

The Lysosome would be the trashcans, the recycle, and the compost. The Lysosome kills bacteria and holds it in plus other waste, and we dispose of our waste by putting it in one of the above options.

The Golgi (apparatus) would be my dad. The Golgi sorts and packages macromolecules to get them ready to transport. My dad does the same sort of thing, he's in charge of kind of organizing/sorting things around the house.

Cell Membrane

The Cell Membrane would be

the doors and the screens (on the windows). The cell membrane is a semi-permeable barrier, meaning that some things can get through and some can't. For example, only people who have the right key can open the door. Also, with the screens, air can get in, but flies and bees can't.

Chloroplast

Cell Wall

The Chloroplasts would be solar panels, if you had any, or houseplants if not. The Chloroplasts convert sunlight into energy, and both houseplants and solar panels do this same job.

If a cell were a house,

the walls, floors, and ceiling would be the cell wall because they keep everything in the house inside, just like the cell wall keeps all the organelles inside the cell.

The pedigree below shows the inheritance of a dominant allele of a gene in a family over several generation. Circles represent f

olga nikolaevna [1]

Complete question:

You will find the pedigree in the attached files

Answer:

The correct option is C) maternal mitochondrial mutations are inherited by all of a mother's offspring.

Explanation:

Mitochondrial inheritance is one of the ways in which a disease or a trait might be inherited from the maternal line.

Most of the DNI is located in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly carry mitochondria, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this DNI, the whole progeny of the mutated woman will be affected, as they will get the mother´s mitochondria carrying the mutation. On the contrary, if there is a man affected by a disease caused by a mutation in mitochondrial DNI, non of their descendants will get the disease.

In the exposed pedigree, we can see that the mother is affected by the disease, but the couple had two daughters, and only one of them was affected, while the other one was not. This tells us that the mutation occurred on a nuclear chromosome. If the mutated allele was in mitochondria, both daughters would be affected.
