Answer:b
Explanation:
From a study of soapberry bugs, evolution can be observed. Soapberry bugs feed on fruits by using their 'beak' to penetrate the fruit and gain nourishment from the seeds within the fruit. Soapberry bugs can feed on the fruit of the balloon vine or the fruit of the Goldenrain tree. In central Florida, the native balloon vine has become rare and the Goldenrain tree is now the main food source for soapberry bugs.
When the beak length of the soapberry bug populations feeding on different fruits was measured after many generations, a difference was noted.
Which of these statements predicts the outcome of evolution based on the food sources for the soapberry bugs? Select ALL that apply.
Answer:
A,C,E
Explanation:

bugs with longer beak, bugs with shorter beaks, access to the seeds
Buds with larger beaks, shorter beaks, and access to seeds predict the outcome of evolution based on the soapberry bugs' food sources. So, the correct options are A, C and D.
What are Soapberry bugs?Soapberry bugs are true bugs who survive on the seeds that grow in the Sapindaceae family. They are distributed throughout the Americas, starting with the southern United States to Argentina.
The body structure and colors of soapberry bugs make them easily identifiable. They are distinguished by their flat bodies and a large, pointed beak or rostrum for piercing the fruit and extracting the seeds. Although their colouring varies, several species have a vivid orange-red or black and white colour pattern.
Because they have been the focus of substantial investigation into rapid evolutionary change, soapberry bugs are essential in the investigation of evolution and natural selection.
Therefore, the correct options are A, C and D.

Answer:
To show that both are evolved from a common ancestor.
Explanation:
It make the comparison between humans and chimps because the two species are so closely related to each other. Humans an chimps evolved from a single ancestor species about six or seven million years ago. Humans and chimps gradually evolved from a common ancestor due to environmental conditions that change their DNA which passed from generation to generation and bring changes in their shape and appearance as well.

O oxigênio é importante um gás na quebra de ligações entre os átomos que formam a glicose para a produção de energia. Por que a presença de ferro no nosso organismo é importante para este processo?
Answer:
It transport oxygen from lungs to the cells.
Explanation:
The presence of iron in our body is very important for this process because iron is responsible for the transportation of oxygen. Hemoglobin is made up of iron that takes oxygen from the lungs to each and every cell. Iron is an essential element for the formation of blood in human body. About 70 percent of body's iron is found in the red blood cells of our blood called hemoglobin and in the muscle cells called myoglobin. So we can say that iron is very important for the release of energy in the process of respiration.

Answer:
D. Evolution
Explanation:
Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

A skeletal and circulatory systems would be my Answer
Explanation:
the skeletal system is responsible for protection, shape, and support. For example the skeletal system protects all some of your most vital organs, such as the brain, lungs, and heart. The skeletal system creates red blood cells which the circulatory system transports. The skeletal system helps the body move.

Explanation:
HIV (human immunodeficiency virus) is a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome).Once inside the T-helper cell, HIV converts its genetic material into HIV DNA, a process called reverse transcription. The new HIV DNA then enters the nucleus of the host cell and takes control of it.

what is the water intake of chlorophytes
Answer:
Huge amount.
Explanation:
There is higher water intake of chlorophytes because the chlorophytes prepare their own food by using water and carbondioxide just like plants in the process of photosynthesis. These chlorophytes have chlorophyll which able these algae to make their food from sunlight and they can't live without water of dry places. Chlorophyte is also known as Prasinophyte which is a green algae. So due to photosynthesis, the chlorophytes needs high amount of water for making food.

A. The products of Photosynthesis are carbon dioxide and water to be used in cellular respiration
B. The reactants of Photosynthesis are the products of cellular respiration
C. The reactants of Photosynthesis are sugar and oxygen to be used in Cellular respiration
D. The products of Photosynthesis are the same as the products of Cellular respiration
Answer: B
Explanation:

¿Qué sucede si una célula se encuentra en la fase G0 del ciclo celular? ¿qué células nunca salen de esta fase?
Answer:
las células en fase G0 no se dividen. Un ejemplo de células en fase G0 son las neuronas y las células del músculo de corazón
Explanation:
El ciclo celular es una serie de eventos asociados al crecimiento y división de una célula. El ciclo celular consta de una fase de crecimiento o 'interfase' (la cual a su vez se divide en 3 fases: la fase G1, S y G2) y la fase de división celular (la cual a su vez se divide en mitosis y citocinesis). Sin embargo, hay células que no entran en fase G1 y en lugar de ello se dirigen a un estadio celular conocido como fase G0. La fase G0 es una es un estadio en el cual se encuentran células maduras que no se dividen hasta recibir un estímulo/señal que dispare la entrada de la célula en fase G1, donde la célula sintetiza los ARN mensajeros y proteínas necesarios para las etapas celulares posteriores que conducen a la división celular. Las células en fase G0 no crecen, pero poseen un metabolismo activo. Ejemplos de células en fase G0 incluyen las neuronas, células musculares poli-nucleadas, hepatocitos, etc. (es decir, células maduras y post-mitóticas que son incapaces de reproducirse).
