Almost all of the corn used for food in the world today comes from the duplication of a few selected genetic strains. Describe one benefit and one drawback of using this method.
Answer:
One benefit is the adaptability and survivability of the corn in a condition that favors this genetic strain.
They are all susceptible to almost the same unfavorable condition and lack adaptability.
Explanation:
Since all the corns have the same genetic strain, this means that they all are closely related and are probably progeny of the same long line of corn. Having the same genetic strain can be favorable if this strain has been selected to suit the conditions of their cultivation area and also to bolster resistance to some dangerous diseases.
In the case where a new condition or disease outbreak is the case, then this is a set back since the genetic strain has not been used to this new conditions. This can lead to extensive damage that may even be close to, if not lead to a complete extinction of this particular corn strain.
Answer:
The benefit is that corn plants will always yield a consistent product because farmers selected against negative genetic characteristics. However, if there’s an environmental change or the threat of a disease, there would be little genetic variation in the crop to improve its chances of survival.

How do jellyfish swim??? How do they glow???
Do they evaporate???
Answer: Most jellies use a form of jet propulsion to move through seawater. ... This is what most jellyfish do. They squeeze their bodies in order to push jets of water from the bottom of their bodies to propel the jellyfish forward. Now check out another method of jellyfish propulsion, used by the comb jellyfish.....Aequorea jellies glow with a bioluminescent protein used in the biotechnology industry. ... Bioluminescence is light produced by a chemical process within a living organism. The glow occurs when a substance called luciferin reacts with oxygen. This releases energy, and light is emitted....Jellyfish seem to blend in with their environment, undulating gently with the ocean's currents, and with good reason: Their bodies are made up of as much as 98 percent water, says How Stuff Works. When they wash ashore, they can disappear after just a few hours as their bodies evaporate into the air.

Predict what you think would happen to your community if a drought occurred. Brainstorm how the physical (abiotic factors/non-living organisms) and biological (biotic factors/living organisms) components of your community could be affected.
Answer:
In my community, if a drought took place, an abiotic factor that would be effected is the soil quality. The soil would dry out which would directly affect biotic factors such as plants and bacteria. The bacteria in the soil could dry out and die. The plants wouldn't be able to drink water and would become dehydrated and not have the ability to maintain homeostasis, causing them to wilt and die.
Explanation:
Scientists have discovered homeotic genes in many kinds of organisms, including fruit flies, mice, and humans. These homeotic genes regulate gene expression and control patterns of development in specific regions of young embryos. Molecular biologists have learned that homeotic genes share a very similar nucleotide sequence, which controls the development of similar portions of fly and mouse embryos. They have found a similar set of genes in humans, which also control corresponding regions of the developing human embryo.
Which of the following statements summarizes a conclusion based upon the evidence contributed by molecular biologists?
Homeotic Genetics
A.
Patterns of development among different animal species did not evolve from a common ancestor.
B.
Humans evolved from flies.
C.
Similar patterns of development increase an organism’s likelihood of surviving and reproducing.
D.
Fruit flies, mice, and humans provide evidence of divergent evolution.
Answer:
D
Explanation:
The presence of homeotic genes shows that all of the listed organisms (mice, flies, humans etc) all evolved from a common ancestor.
(A) is wrong as the evidence of the same gene existing in vastly different species shows the evolutionary relationship between these organisms.
(B) is wrong as there is insufficient evidence to prove that flies are the precessor of humans. We do know that flies and humans have evolved from a common ancestor though.
(C) is non-conclusive as the passage said nothing about the gene allowing the species to have a higher chance of surviving and reproducing. Hence, an errornous claim.
(D) is the correct answer as from a common ancestor, all of the listed organisms undergo and accumulates mutation, undergoes selective pressures that resulted in divergent evolution (aka branching evolution that results in many noval species forming) after millions of years.

Answer:
Volume of rectangular prism = 81 feet³
Explanation:
Volume of rectangular prism is same as volume of cuboid
Length = 9 ft
Width = 4 ft
Height = 2 [tex] \frac{1}{4} [/tex] ft = [tex] \frac{9}{4} [/tex] ft
Volume of rectangular prism = Length × Width × Height
= 9 × 4 × [tex] \frac{9}{4} [/tex]
= 36 × [tex] \frac{9}{4} [/tex]
= [tex] \frac{324}{4} [/tex]
= 81 feet³

Each pair of clay balls represents two planetesimals. If each planetesimal is composed of the same material and is separated he the same distance, which pair experiences the frayed gravitational attraction?
Answer:
Every object that has mass exerts a gravitational pull on the objects around it. Depending on how big the object is, more the pull it exerts will be in magnitude. A massive object such as the Earth will inevitably overwhelm all other gravitational attraction caused by objects on it. In this case of planetesimals, even though the materials are the same, the mass must be different for one to experience a greater gravitational attraction than the other.

3) Scientists who have examined the fossil record have noted that some species have changed very little over long
periods of geologic time. The lack of change in such organisms is most likely because
A) the environment that they lived in remained the same, and they were well-adapted to it
B) all members of their population were genetically identical, and they lived in a rapidly changing
environment
C) there was a large amount of variation in their population, and the environment changed frequently
D) they could move between different environments when food supplies became scarce
Answer:
The correct answer is option A) "the environment that they lived in remained the same, and they were well-adapted to it".
Explanation:
One of the basis of evolution is that species that face new environmental conditions tend to develop new traits to survive. The opposite applies to species that have lived in constant environmental conditions, these species are usually well-adapted and have changed very little over long periods of geologic time. Some species of tortoises are examples of animals that had changed very little in their evolutionary history. The hard shells of tortoises is an ancient adaptation that help them to survive in constant environmental conditions.
The lack of change in organisms in some species examined by scientist is most likely because A) the environment that they lived in remained the same, and they were well-adapted to it
What is adaptation?Adaptation can be regarded as the biological mechanism whereby organisms adjust to new environments or to changes in their current environment.
Therefore, the reason why some species have changed very little over long periods of geologic time is due to adaptation.

Frontal lobe
Parietal lobe
Answer:
I believe it is the Parietal lobe
Explanation:
It knows reading, sensation, body oreintation and knowing left from right.
The human brain just like most other mammals has the same basic structure. But it is better developed than any other mammalian brain. The part of the brain highlighted in the diagram below is Parietal lobe. The correct option is D.
What is brain?The brain along with the spinal cord constitutes the central nervous system. It is responsible for the thought, interpretation and control of our body movements. It is located within the skull which provides frontal, lateral and dorsal protection.
The human brain controls and coordinates all the physiological functions to cognitive abilities. It performs by sending and receiving signals through neurons to different parts of the body.
The parietal lobe rests near the top and center of the cerebral cortex, that is just behind the frontal lobe and above the occipital and temporal lobes. The parietal lobe is vital for the sensory perception and integration.
Thus the correct option is D.

Scientists are concerned about the rising levels of carbon dioxide (CO 2). What trait about this gas makes it so concerning to scientists?
Answer:
It is a greenhouse gas i.e. Its ability to contribute to Global Warming.
Explanation:
Carbondioxide (CO2) is one of the world's colorless, odorless and tasteless gases in air. It is the major product of cellular respiration by living organisms. The increase in level of CO2 in the atmosphere is a major concern to scientisits because they have the ability to trap heat, hence, called a GREENHOUSE GAS.
CO2, in conjunction with other gases like methane, are responsible for keeping the earth warm as they help trap heat energy from the sun. However, an increase in the level of these greenhouse gases is contributing to what is called Global Warming, which is the gradual increase in the temperature of the earth's atmosphere.

Explain the relationship between the sensors, control center communication systems and targets when maintaining homeostasis.
Answer:
Homeostasis es la constancia del Medio interno, aún frente a las variaciones del Medio externo
(Cannon). El Medio interno se relaciona con la complejidad de los seres vivos.
Según Teoría de la Evolución, el primer ser vivo surgió en el mar, formado por una sola célula, la cual
intercambiaba nutrientes y desechos metabólicos con su Medio externo.
De los Unicelulares evolucionaron los Pluricelulares, los cuales debían solucionar el problema del
intercambio de nutrientes, oxigeno y desechos de las células que se encuentran en su interior. De esta
forma se desarrolló un ambiente interno, que permitió la vida libre e independiente.
El Medio interno está representado por el Líquido extracelular que rodea a las células de los Pluricelulares,
con una composición estable que permite los intercambios metabólicos y la comunicación celular.
El 60 % del peso corporal humano es agua, la cual se encuentra distribuida en un 40% del peso corporal en
el Líquido intracelular y en un 20% en el Líquido extracelular.
Del total del Líquido extracelular un 80% corresponde al Líquido intersticial y un 20% al Plasma sanguíneo.
El Líquido intersticial o tisular debe mantenerse constante, para lo cual se requiere la ayuda del
Sistema circulatorio.
El Plasma sanguíneo intercambia oxigeno y nutrientes, dióxido de carbono y desechos con el Líquido
extracelular a nivel de los Capilares sanguíneos, debido a lo cual en ambos líquidos la concentración de
solutos es igual, a excepción de las proteínas.
Según Starling, existe un equilibrio entre el volumen de líquidos que sale del capilar arterial y el que
vuelve por los capilares venosos.
El Líquido intracelular varía de célula a célula del punto de vista cuantitativo, guardando similitud en la
composición celular desde el punto de vista cualitativo
