in order to increase chances of survival in a changing environment, it is important for a species to have
Answer:
One key way by which species evolve over time in response to changes in environmental conditions is adaptation by natural selection acting over generations. Characteristics that aid in effective survival and reproduction in the new environment grow more prevalent, while those that do not become less prevalent.

Entre una planta alta de color purpura (AABB) con otras planta enana de color blanco (aabb), ¿cómo será el genotipo y el fenotipo de la F1 Y F2?
Answer:
- Alelos:
Locus 1: A (alto); a (enano)
Locus 2: B (púrpura); b (blanco)
- Cruzamiento parental: AABB x aabb
Genotipos F1: AaBb
- Cruzamiento F1: AaBb x AaBb
Fenotipo: 100% plantas altas púrpuras
- Genotipos F2: AABB (1/16); Aabb (1/16); aaBB (1/16); aabb (1/16); AaBb (4/16); AABb (2/16); aaBb (2/16); AaBB (2/16); Aabb (2/16)
- Fenotipos F2: 9/16 A-B- (altas púrpuras); 3/16 A-bb (altas blancas); 3/16 aaB- (enanas púrpuras); 1/16 aabb (enanas blancas)
Explanation:
Un cruzamiento dihíbrido refiere a un tipo de cruzamiento entre dos parentales que difieren para dos pares de alelos (AABB x aabb). Si consideramos dos loci de dominancia completa, un cruzamiento dihíbrido producirá una F1 heterocigota para ambos genes donde la progenie expresará ambos rasgos dominantes. Como resultado de la distribución independiente expresada en la segunda ley de Mendel, La F2 de este tipo de cruzamiento producirá un proporción fenotípica 9:3:3:1; es decir 9 individuos con ambos rasgos dominantes (A-B-), 3 con el rasgo uno dominante (A-bb), 3 con el rasgo dos dominante (aaB-) y 1 con ambos rasgos recesivos (aabb).
Our atmosphere acts like a blanket trapping heat and keeping Earth at a habitable temperature, it’s this retaining of heat that is referred to as the Greenhouse Effect. The greenhouse effect is caused by greenhouse gases that trap heat from the sun, the more greenhouse gases there are the more heat is retained
HOW IT WORKS
The heat from the sun (solar radiation) has a very short wavelength and this can pass easily through the layer of greenhouse gases. This wavelength is called Ultraviolet radiation. As the UV rays strike the Earth, the Earth redirects the rays back into the atmosphere. We feel this as heat. The heat from the earth (terrestrial radiation) has a longer wavelength (infrared) some of this becomes trapped by the layer of greenhouse gases.
GREENHOUSE GASES
Water vapor (H20) is the most prevalent greenhouse gas and occurs naturally. Some greenhouse gases are both natural and man-made including carbon dioxide (CO2) & methane (CH4).
Describe the size of insolation when it strikes the Earth.
What would happen if there were no greenhouse gases to trap heat?

The exploration of the mid-Cayman rise is intended to discover _______. a. what life may have been like before the evolution of photosynthesis b. the origins of photosynthesis c. life in shallow, coastal regions d. the chemical composition of undersea mountains Please select the best answer from the choices provided A B C D
Answer: a. what life may have been like before the evolution of photosynthesis
Explanation:
The mid-Cayman rise is an area that has little light coming in but still has life in it.
Plants are able to provide food for themselves and the rest of us by using photosynthesis to make food. Photosynthesis uses sunlight to make this food.
One would think that photosynthesis was around for as long as plants were around but this is not the case. Life on earth had existed long before photosynthesis became a valuable process to plants.
There is therefore curiosity as to how this life fed itself without using photosynthesis and this is why the life in the mid-Cayman is being explored. The way the life makes food there in the absence of light will shed light on how plants made food before photosynthesis.

É correto afirmar que a presença de lagartas em espigas de milho se deve:
A - ao processo de geração espontânea comum aos invertebrados.
B - à transformação dos grãos em lagartas.
C - ao desenvolvimento de ovos depositados por borboletas.
D - ao apodrecimento do sabugo e dos grãos.
Answer:
C - ao desenvolvimento de ovos depositados por borboletas.
Explanation:
Antes de responder a sua pergunta, eu preciso te explicar que esse não é o servidor brasileiro e sim o servidor dos EUA, você deve ter percebido que toda a linguagem do site esta em inglês. Isso significa que você só deve postar perguntas em português no campo "World Languagens" mesmo que a sua pergunta seja de biologia como essa. Caso você não faça isso, a sua pergunta pdoe ser excluída, sem ser respondida.
As lagartas que surgem nas espigas de milho, são resultado do ciclo de vida da lagarta e refere-se ao momento em que os ovos depositados nas plantas de milho pelas borboletas se chocam, liberando as lagartas, que se desenvolverão e virarão novas borboletas.
É impossivel que um grão e milho vire uma lagarta, ou que o sabubo apodrecido pode gerar lagartas. Além disso, o ´processo de geração espontanea é uma teoria cientifica invalida e que não deve ser considerada.

HELP! What evidence indicates that many psychological disorders, such as schizophrenia and developmental
disorders, are biologically and not environmentally based?
Answer:
Schizophrenia and developmental disorders are traced genetically, and the gene will be found in the biological parents of the person with either schizophrenia or developmental disorders.
Explanation:
Although Schizophrenia can be triggered by environmental factors, or the 'nurture' of childhood development, a person who is not predisposed genetically to schizophrenia will not get the psychological disorder. The same is to be said about developmental disorders such as Autism and ADHD, it is hereditary.
For citation of evidence, I recommend talking about prenatal development, and how toxic substances can alter the development of a fetus, which is proven to lead to some developmental disorders, such as Fetal Alcohol Syndrome.
Answer:
Schizophrenia and developmental disorders are genetically connected, and the gene will be found in either the individual's biological parents or the person suffering from schizophrenia or developmental abnormalities.

Explain the difference: a myelinated axon conducts impulses faster than non-myelinated axon of the same diameter
Answer:
A myelinated axon conducts impulses faster than a non-myelinated axon. ... Therefore, in myelinated neurones, the nerve impulse is said to jump from node - to - node, a impulse pathway known as Saltatory Conduction. This means that the action potential does not have to travel along the whole length of the myelinated axon

which feature of stem cells enable them to replace cells in tissues such as skin?
The feature of stem cell which enable them to replace cell in tissues are that they can divide indefinitely to generate new cells and they can convert into the different types of cells that make up the body as they divide.
What is a stem cell ?A stem cell is a cell that has the unique capacity to grow into different types of cells in the body.
They may be utilised in the future to replace cells and tissues that have been damaged or destroyed owing to illness.
Stem cells are classified into three types which are Embryonic stem cells, Adult stem cells, Induced pluripotent stem cells.
Embryonic stem cells provide new cells to an embryo as it grows and develops into a newborn.
Adult stem cells generate new cells as an organism matures and replace damaged ones.
Induced stem cells are stem cells created in the laboratory by scientists.

Answer:
word to my dead When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.
