Explanation:

Answer: Los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.

Explanation:

Un gen es un segmento de ADN que codifica para una proteína. Para cada gen, hay distintas versiones, conocidos como alelos. Por ejemplo, el gen que codifica para el pelaje tiene los alelos para el color blanco y para el color negro. Considerando que los organismos diploides tienen dos copias de cada gen (dos alelos), un alelo dominante solo necesita una copia para expresarse. Mientras que un alelo recesivo, necesita dos copias.

En este ejemplo, el borrego homocigota blanco tiene un genotipo (conjunto de genes) de AA ya que el color blanco es dominante y al ser homocigota indica que ambos alelos son iguales. El borrego homocigota negro tiene un genotipo de aa ya que se necesitan dos alelos recesivos para mostrar ese fenotipo (características visibles).

Los borregos producen gametos, los cuales son células sexuales (espermatozoide u óvulo) haploides, es decir que solo poseen un alelo de cada gen. Entonces el borrego AA solo produce gametos con genotipo A, mientras que el borrego aa solo produce gametos con genotipo a. Estos gametos son los que se cruzan, es decir que la descendencia solo puede tener un genotipo Aa (con un alelo de cada padre)

El genotipo Aa posee un alelo dominante A (que codifica para el color blanco) que enmascara los efectos de el alelo recesivo a (que codificaría para el color negro) Entonces, los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.

Answer:

b . chemical weathering

Explanation:

Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.

Answer:

D.

Explanation:

You can rule out B and C because offspring produced sexually are not identical to their parents. The amoebas reproduce by binary fission, which is a form of asexual mitosis.

Answer:

D. asexually by the process of MITOSIS

Explanation:

Mitosis is a form of asexual reproduction in simple living organisms. The outcome of each cell cycle is two identical cells. Mitotic checkpoints happen at certain stages of mitosis to ensure that each cell receives the same amount of DNA.

Answer:

A. True

Explanation:

Yeah, we don't know what the first life form was or how it came to be, but the process of reproduction with VARIATION over billions of years is responsible for the diversity of life on Earth today.

c The movement of energy between organisms

Explanation:

Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.

The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).

This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.

Furthermore, a list of the types of organisms in an eco pyramid are;

I. Producers: these are autotrophs or self-feeders such as plants.

II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.

III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.

IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.

Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.

Explanation:

In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,

Grass-------> Zebra ---------> lion

(Primary (Primary ( secondary

producer). consumer) consumer)

this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.

Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.

Ammonification is crucial for providing living organisms with the essential nitrogen that they need.

Answer:

Eukaryotic cells have a membrane-bound nucleus.

Prokaryotic cells do not. The nucleus is where Eukaryotic stores their genetic information.

Answer:

moving across both the plasma membrane and the outer membrane

Explanation:

Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.

Answer:

B. Different genes are expressed due to their environment.

Explanation:

Some identical twins can have different heights and weights. This is because height and weight are controlled by what you eat as well your DNA. Differences in diet can start earlier than you might imagine. When the twins are growing inside the uterus, there can be differences in how well they connect to the placenta.

C. Red

Explanation:

Red colour on the map shows the Mid Atlantic Ridge. The Mid-Atlantic Ridge  is also called as a mid-ocean ridge. It is an underwater mountain system formed due to plate tectonics. It is created due to a divergent plate boundary that started from 87° N about 333 km to the south of the North Pole which is 54 °S, which is north of the coast of Antarctica. In the picture, the red colour is the line that shows Mid Atlantic Ridge.

Answer:

C. A protein

Explanation:

The outcome of protein synthesis is a protein.

The process of protein synthesis is crucial to cellular function. Protein synthesis is the procedure used by cells to generate proteins. Thus, option C is correct.

Protein synthesis, sometimes referred to as protein biosynthesis, is an essential biological process that occurs inside of cells to replace lost proteins (due to export or degradation) with new proteins.

Proteins have a wide range of vital biological functions, including those as enzymes, hormones, and structural proteins.

Cells are made of proteins, and the word “synthesis” simply means “to make.” Thus, the process of producing proteins is known as protein synthesis.

Creating a polypeptide, or protein consisting of a chain of amino acids, is the sole goal of protein synthesis. Keratin, a protein, is produced in the cells of the hair follicle.

Therefore, The outcome of protein synthesis is a protein.
