As skeletal muscle is further stretched beyond the length where optimum force is developed, ________. the thick filaments overlap one another, thereby reducing their ability to interact with actin the thin filaments overlap one another, thereby reducing their ability to interact with myosin the thick filaments are pulled away from one another, thereby reducing their ability to interact with actin the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin the amount of calcium released by the sarcoplasmic reticulum is reduced as length increases

Answers

Answer:

the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin

Explanation:

The myofibril is the basic unit of a muscle cell. Each myofibril is composed of contractile units known as sarcomeres which may contain two different types of myofilaments: thick myofilaments and thin myofilaments. The thick filaments are known to have a constant length, and they consist especially of myosin proteins. These filaments (thick) do not extend to the ends. On the other hand, the thin filaments extend in from each end, and they are mainly composed of actin proteins that serve as tracks for the movement of myosin proteins.

Why would scientists conduct research on a newly discovered alternative fuel?

A. To maintain the public dependence on fossil fuels
B. To maintain the success of the petroleum industry
C. To confirm that the alternative fuel is cleaner than fuels currently used
D. To confirm that the alternative fuel increases atmospheric carbon dioxde.

Answers

Answer:

C. To confirm that the alternative fuel is cleaner than fuels currently used

Explanation:

The current fuels from mining, cutting down trees and even transportation is bad for the atmosphere. These fuels cause climate change which could potentially bring a lot of dangers. The reason scientists would conduct research on a newly alternative fuel is so that the fuel would be a lot more cleaner which could prevent the dangers that are to come.

The modern synthesis combined the concepts of _______ and evolution. If a population is at Hardy-Weinberg equilibrium, the allele frequencies must be _______.

Answers

Answer:

The correct answer would be - genetics, constant.

Explanation:

The modern synthesis is a unified evolution theory that came forward by the fusion of Mendelian genetics with Darwinian evolution. It is focused on the genetic basis of evolution as it defines evolution as changes in the allele frequency in the population.

If a population is at Hardy-Weinberg equilibrium, the allele frequencies remain the same in the population unless there is no change is applied to it. It will remain constant only if there is no mutation, infinite population size, no gene flow, random mating, and no selection.

Answer:

1. natural selection

2. constant from generation to generation in the absence of other evolutionary influences.

Como resultado del proceso de la fotosíntesis se elimina a través de los estomas a La glucosa b) El oxígeno. C) El dióxido de carbono d ) Oxígeno y dióxido de carbono

Answers

Answer:

Como resultado del proceso de la fotosíntesis se elimina a través de los estomas el oxígeno.

Explanation:

La fotosíntesis es un proceso metabólico que llevan a cabo determinadas células de organismos autótrofos, es decir, aquellas que tienen la capacidad de producir su propio alimento, como las plantas. Con este proceso, las plantas captan la energía de la luz solar y la transforman en energía química, para producir materia orgánica a través de materia inorgánica.

Los procesos que llevan a cabo las plantas en la fotosíntesis se llevan a cabo en 2 etapas: en la primera etapa las plantas absorben el agua del suelo a través de las raíces. A través de sus tallos lo transportan hasta sus hojas. En estos se encuentra el pigmento llamado clorofila, que además de darle a la hoja el color verde, capta la luz solar y rompe la molécula de agua (H₂O), separando el hidrógeno (H) del oxígeno (O₂). En esta etapa se almacena energía y se libera oxígeno al medio ambiente.

La otra etapa es capturar dióxido de carbono. Esto proporciona los átomos de carbono y oxígeno que, junto con el hidrógeno y la energía almacenada, formarán la molécula de glucosa.

Entonces, los estomas son poros en la superficie de las plantas, encontrándose mayoritariamente en las hojas y en menor medida en los tallos y otros órganos. En ellas transcurre el intercambio gaseoso mecánico, es decir que en este lugar sale el oxígeno y entra dióxido de carbono en la fotosíntesis.

Por lo que, como resultado del proceso de la fotosíntesis se elimina a través de los estomas el oxígeno.
