Answers

Complete question:

Sea urchins belong to the echinoderm phyla. Adult sea urchins have spines that extend outward from their exoskeleton, but as larvae, the sea urchins have only an exoskeleton made from spicules. The spines offer protection against predators. Sea urchins typically spawn near the surface. Males release sperm into floating plankton, then female urchins release between eight and 20 million eggs in the same area. The jelly-like coating on the eggs attracts the sperm, and when the two meet, they create an embryo that starts dividing into new cells within minutes.

Based on the information the population size of sea urchins is low in relation to the carrying capacity of the area. As a result, the sea urchins are

A) r-strategists that allocate much energy toward parental care.

B) r-strategists that allocate energy to producing many young.

C) density-independent because there is plenty of energy.

D) irruptive, because their numbers crash quickly.

Answer:

B) r-strategists that allocate energy to producing many young.

Explanation:

According to the given information, this species expresses survival curve type III, characteristic of r-strategists. Males and females release many gametes into the sea. If these gametes get to meet, they produce the embryo that starts developing. But there are high chances for these new organisms to die. Significant mortality during the early stages of life is expected for the species. The few individuals that manage to reach the later life stages, getting to survive, usually have a long life. These species produce many gametes to release, which results in the production of many offspring simultaneously. However, adult individuals provide no parental care. Their success in reproduction depends on the number of surviving descendants.

Males release sperm into floating plankton, Female urchins release between eight and 20 million eggs in the same area,When they meet, sperm and egg create an embryo that starts dividing into new cells within minutes.

We might also mention that the population size is under the carrying capacity. r-strategist choose to live in areas with only a few individuals, where nitches are hardly occupied.

Sheets composed of two layers of amphipathic molecules arranged with the hydrophilic groups on the surface and the hydrophobic groups buried in the center that form in water are called A) micelles. B) liposomes. C) vacuoles. D) bilayer membranes. E) none of the above

Answers

Answer:

D) bilayer membranes

Explanation:

Two lipidic bilayers compose the cell membrane. There are also proteins and glucans incrusted in between. Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. Membranes are fluid, which means that the composing molecules can move through them.

Lipids can easily change places with other neighboring lipids by lateral diffusion in the same layer. This is passive diffusion, which means that it does not need energy to happen.

Lipids can also diffuse transversally to the other layer but not as easily as lateral diffusion. Jumps between monolayers are infrequent as the lipidic polar heads meet the fatty acid barrier.

There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.

A small size is advantageous for marine organisms because it ________. increases the surface area to volume ratio that in turn reduces frictional resistance to sinking increases the ability to absorb nutrients increases the ability of wastes to diffuse out of the organism All of the above

Answers

Answer:

increases the ability of wastes to diffuse out of the organism

Explanation:

A small size of an organism is advantageous for marine organisms because it increases the ability of wastes to diffuse out of the body of organism. Small size of an organism produces less amount of waste material and these organism does not need a very special and complex excretory system so simple diffusion of waste material occurs from the body in order to clean the body.

5. 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³ (electrones de valencia) Grupo: 15 Periodo: 4

Explanation:

La configuración electrónica de los elementos es la disposición de todos los electrones de un elemento en niveles y subniveles de energía (orbitales).

Hay 7 niveles de energía, numerados del 1 al 7, y en los que los electrones se distribuyen, lógicamente, en orden según su nivel de energía. Los electrones con menos energía girarán en el nivel 1. Cada nivel se divide en subniveles. Estos subniveles en los que se divide cada nivel pueden ser hasta 4. Estos 4 subniveles se denominan: s, p, d, f. En el subnivel s solo puede haber un máximo de 2 electrones, en p puede haber un máximo de 6 electrones, en el subnivel d 10 electrones y finalmente en el subnivel f puede haber un máximo de 14 electrones.

Por otro lado, los electrones de valencia son los electrones que se encuentran en la última capa electrónica (denominada orbitales de valencia) y tienen muchas posibilidades de participar en una reacción química.

En la tabla periódica, en cada período aparecen los elementos cuyo último nivel de su configuración electrónica coincide con el número del período, mientras que en cada grupo aparecen los elementos que presentan el mismo número de electrones en el último nivel ocupado o capa de valencia. Entonces:

1. 1s² Grupo: 18  Periodo: 1

2. 1s²2s²2p⁶3s¹ Grupo: 1 Periodo: 3  

3. 1s²2s²2p⁶3s²3p⁶4s² Grupo: 2 Periodo: 4

The active site of an enzyme is _____________. Group of answer choices the region of an enzyme that attaches to the product the region of a product that detaches from the enzyme the region of a substrate that is changed by an enzyme the region of an enzyme that attaches to a substrate the highly changeable portion of an enzyme that adapts to fit the substrates of various reactions

Answers

Answer: The correct option is (the region of an enzyme that attaches to a substrate).

Explanation:

The anabolic and catabolic processes in a cell are directed and regulated by enzymes. An enzyme has the ability to speed up a metabolic reaction by lowering the amount of energy needed to start the reaction. Without enzymes, these processes would be extremely slow. They also arrange the reacting molecules in a manner that will cause the chemical change to take place rapidly. It does so through the following steps:

--> molecules of substrate combine with the enzyme at its active site.

--> the substrate molecules combine with enzyme molecules for a short time, forming an enzyme-substrate complex.

--> New substance ( product) is formed which leaves the active site of the enzyme thereby making it free for another reaction to take place.

In conclusion, the ACTIVE SITE of an enzyme is the region of an enzyme that attaches to a substrate allowing chemical reaction to take place.

Nitrogen fixation converts nitrogen gas to usable nitrogen for plants?

True
False

Answers

Answer:

True, nitrogen fixation converts atmospheric nitrogen into nitrogen that can be used by plants.

Explanation:

Think about water. There's plenty of water on Earth, but very few is actually drinkable, at least for humans. So we have to fix it by filtering out dangerous bacteria in the water and other dangerous stuff before being able to actually drink it. Same with atmospheric nitrogen. It must be "fixed" before plants can actually use them.

An actin-binding protein called cofilin binds preferentially to ADP-containing actin filaments rather than ATP-containing actin filaments. Based on this preference, which is true? Question 7 options: Cofilin binds to the plus ends of treadmilling actin filaments. Cofilin competes with profilin for binding to actin. Cofilin binds to older actin filaments. Cofilin binds to the plus ends of actin filaments.

Answers

Answer:

Cofilin binds to older actin filaments

Explanation:

Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.
