6. The Edwards Plateau in west-central Texas is home to a diverse group of bats, reptiles,
and birds. How does the biodiversity of the Edwards Plateau affect the sustainability of local
ecosystems?
A. The variety of interactions among the different species helps the ecosystems remain
sustainable.
B. The variety of interactions among the different species prevents the ecosystems from being
sustainable.
C. The uniformity of interactions among the different species prevents the ecosystems from
being sustainable.
D. The uniformity of interactions among the different species helps the ecosystems remain
sustainable.
Answer:
A.
Explanation:
The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.

briefly explain natural selection
Answer:
Explanation:
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

the wing of a penguin is ________ the arm of a human.
The wing of a penguin is homologous to the arm of a human.
Homologous organs refer to organs of different organisms that are structurally similar but functionally different.
The wing of a penguin and the arm of a human are structurally similar because they are both built on the same pentadactyl or five-digit plan.
Despite the structural similarity, the wing of a penguin and the arm of a human are adapted for different functions. While the wings of a penguin are used to propel the animal in water by flapping them together, the arms of a human are adapted for several functions, including swimming when necessary.

Scientists studied the evolution of horses. They concluded that horses evolved with the emergence of grasslands and an increase of predators. The digits of their early Eocene ancestor evolved into hooves. The diet changed from foliage to grasses. The molar teeth developed and became stronger. Which statements are supported by this evidence?
A) Molars became bigger to fit into the jaw structure of modern horses.
B) The molars of the horses underwent changes so they could chew meat.
C) The digits were modified to enable the horses to graze better on hard, rocky surfaces.
D) The emergence of grasslands over time led to the development of strong molar teeth in horses.
E) The digits of the horses’ feet underwent modifications, enabling them to run faster from predators.

Con đường vận chuyển nước vậy ông chất khoáng qua thành tế bào sang bào ở thực vật có đặc điểm gì
Answer:
In plants, minerals and water are transported through the xylem cells from the soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts. Thus, there is continuous water movement into the xylem.
Bài giải:
Ở thực vật, các chất khoáng và nước được vận chuyển qua các tế bào xylem từ đất đến lá. Các tế bào xylem của thân, rễ và lá liên kết với nhau tạo thành một kênh dẫn đến tất cả các bộ phận của cây. Do đó, có sự chuyển động liên tục của nước vào xylem.

Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She
explained the process in the following steps.
1. DNA is transcribed into mRNA.
2. Amino acids form a chain.
3. The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
O Polypeptide chains express gene traits.
O tRNA delivers the DNA to the ribosome.
hy
O DNA is replicated into two daughter cells.
O mRNA is translated into amino acids.
The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
TranscriptionTranslationDuring transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

qual é o resultado da meiose ?
Answer:
El proceso da como resultado cuatro células hijas que son haploides, lo que significa que contienen la mitad del número de cromosomas de la célula madre diploide. La meiosis tiene similitudes y diferencias con la mitosis, que es un proceso de división celular en el que una célula madre produce dos células hijas idénticas. Espanol
English: The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

Which factor contributes to the formation of tides that turn turbines to create energy in the ocean?
wind speed
water density
Earth’s rotation
water temperature
The factor that contributes to the formation of tides that turn turbines to create energy in the ocean is Earth's rotation.
What is Tidal energy?Tidal energy is a type of renewable energy that is generated by the movement of water due to the gravitational forces of the moon and the sun.
As the Earth rotates, the gravitational forces of the moon and the sun cause the water in the ocean to move, creating tides that rise and fall twice a day.
This movement of water can be harnessed by turbines, which are placed in areas of high tidal flow. As the tides move in and out, the turbines spin, generating electricity that can be used to power homes and businesses.
While factors such as wind speed, water density, and water temperature can all affect the movement of water in the ocean, they are not the primary factors that contribute to the formation of tides.
The tides are primarily driven by the gravitational forces of the moon and the sun, which cause the water to move in a predictable pattern that can be harnessed for energy generation.
