Mechanical Defenses
The first line of defense in plants is an intact and impenetrable barrier composed of bark and a waxy cuticle. Both protect plants against herbivores. Other adaptations against herbivores include hard shells, thorns (modified branches), and spines (modified leaves). They discourage animals by causing physical damage or by inducing rashes and allergic reactions. Some Acacia tree species have developed mutualistic relationships with ant colonies: they offer the ants shelter in their hollow thorns in exchange for the ants’ defense of the tree’s leaves.
Which of the following is not an appropriate unit for momentum?
A. g • cm/min
B. g • m/S
C. km • m/S
D. kg • m/hr
Answer:
Option C us correct.
km • m/S
Explanation:
This is because momentum is result of mass and velocity of an object. Momentum is a vector quantity that is it has magnitude and it's direction is in form of three dimensional.
From the option C, kilometer there is not a unit for mass or velocity it it is a unit for distance, therefore it is incorrect.
The initial step in the formation of an aminoacyl-tRNA is Group of answer choices esterification of the tRNA activation of the tRNA by reaction with ATP activation of the amino acid by reaction with ATP interaction of the mRNA with the tRNA
Answer:
The initial step in the formation of an aminoacyl-tRNA is activation of the amino acid by reaction with ATP
Explanation:
In protein synthesis, the first step involves the formation of an aminoacyl-tRNA. This reaction is catalyzed by the the Mg²⁺-dependent enzymes known as aminoacyl t-RNA synthetases and occurs in two steps.
The first step of the reaction of the formation of an aminoacyl-tRNA is the activation of the amino acid by the attachment of an AMP molecule formed from the hydrolysis of ATP to AMP and pyrophosphate. The aminoacyl adenylate intermediate is bound to the enzyme in this initial step. Subsequently, in the second step of the activation of the amino acid, the aminoacyl adenylate intermediate is then transferred to its specific tRNA. The pyrophosphate formed in the first step is hydrolyzed to 2 phosphate molecules by a pyrophosphatase.
The overall reaction step is illustrated below:
Amino acid + tRNA + ATP -----> aminoacyl-tRNA +AMP + 2Pi

Si la filosofia es un saber acerca de las cosas desde un punto de vista universal, entonces dificilmente sea ciencia
Explanation:
Esta afirmación es correcta, porque si bien la ciencia se deriva de la filosofía, la filosofía es la necesidad humana de obtener conocimientos y así desarrollar un pensamiento racional, crítico y diferente al sentido común, y por tanto se conceptualiza como algo más subjetivo, cultural y más amplio que la ciencia. , que se basa en hechos y estudios para respaldar un análisis. A través de la filosofía es posible desarrollar la ciencia, pero son cosas diferentes porque la ciencia está ligada al empirismo y la filosofía es más amplia y comprensiva.

Which of the following is most likely to contribute to density-dependent regulation of populations? Group of answer choices Individuals voluntarily stop mating so that overcrowding does not occur. Density-independent factors lead to fewer births and increased mortality. The incoming energy decreases in populations experiencing a high rate of increase. Density-dependent factors lead to fewer births and increased mortality.
Answer:
Density-dependent factors lead to fewer births and increased mortality.
Explanation:
The carrying capacity can be defined as the maximum population size an environment can support. Density-dependent limiting factors produce a logistic growth pattern (S curve) in the population until it reaches its carrying capacity, thereby decreasing the birth rate and increasing the mortality rate in the population. Some important density-dependent limiting factors able to control the size of the population are competition (intraspecific competition), predation and diseases.

1. What is the gradual change in populations over time?
2. What is the idea that species originate in small gradual steps over time?
1. Gradualism
2. evolution
Answer:1.Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in a slow and consistent process of change in the whole population.
2.Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).

Which of the following statements is true?
Fusion reactions split hydrogen nuclei apart.
Fission reactions release more energy than fusion reactions.
Nuclear power plants change electricity into nuclear energy.
U-235 is an isotope of uranium.
Answer:
Fission occurs when a neutron slams into a larger atom, forcing it to excite and spilt into two smaller atoms—also known as fission products. Additional neutrons are also released that can initiate a chain reaction.
When each atom splits, a tremendous amount of energy is released.
Uranium and plutonium are most commonly used for fission reactions in nuclear power reactors because they are easy to initiate and control.
The energy released by fission in these reactors heats water into steam. The steam is used to spin a turbine to produce carbon-free electricity.

Which two structures are part of the cortisol pathway?
Each gland consists of two parts: an inner medulla, which produces epinephrine and norepinephrine (adrenaline and noradrenaline), and an outer cortex, which produces steroid hormones.
The structures that are part of the cortisol pathway are the hypothalamus and liver.
Cortisol is a glucocorticoid in the brain with the function of operation of Gluconeogenesis and stress. The pathway of cortisol in the body is termed as cortisol pathway.
What structures are in the Cortisol pathway?The cortisol pathway is started with the release from the brain, targeting the hypothalamus. The release of epinephrine and nor-epinephrine is controlled with the cortisol release.
The release of the hormones targets the pituitary and adrenal gland and controls the release of stress hormones.
The gluconeogenesis process is controlled by the cortisol hormone. The process takes place in the liver.
Thus, the structures that are part of the cortisol pathway are the hypothalamus and liver.
