how scientists are able to determine climate information by just looking at tree rings? (how does it work?)
Explanation:
Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that area's local climate in the past. For example, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry.
Answer:
Explanation:
Climate scientists compare the tree growth records to local weather records. For locations where a good statistical match exists between tree growth and temperature or precipitation during the period of overlap, the ring widths can be used to estimate past temperature or precipitation over the lifetime of the tree.
There are marked differences in the type of organisms found at four different locations at the same tidal height along ta rocky shore. What might account for this
Answer and Explanation:
Many elements can be responsible for this, among them, we can mention the presence and absence of predators in the different places on the rocky coast. This is because predators can influence not only the number of organisms found, but also the types of organisms.
Another element that may be the cause of this variability is the availability of resources necessary for the life of these organisms, in addition, the impact of the waves on the rocks, can cause the variability of the organisms, since some may not be able to resist the impact of the waves.
Which of the following is the best example of homeostasis in the human body?
Answer:
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius).

Explanation:
Fluorescent FM dyes partition reversibly into biological membranes without penetrating through them. Suppose that you have neurons cultured in a dish, and you incubate them with an FM dye for a period of time before washing the cells with excess medium to remove the dye.a)You find that if you stimulate the neurons to trigger action potentials during incubation with the dye, the synaptic regions of the neurons remain fluorescent after the wash. Propose an explanation for this effect.b)After you have generated fluorescent synaptic regions by this procedure, suppose that you trigger further action potentials while continuing to wash with excess medium. Would you expect the synaptic regions to lose fluorescence
Answer:
a) Emission observed is due to emission of synaptic vessels
b) Yes
Explanation:
a) Proposing an explanation
The emission observed ( the synaptic regions of the neurons remaining fluorescent ) is due to the emission on the synaptic vessels given that FM dyes have lipid-sensitive emission which can be loaded into a recycled synaptic vesicle
b)
The synaptic regions will lose fluorescence when you continue to wash with excess medium, also the more action potentials triggered the more observed emission. hence the increase in the loss of fluorescence is due to the fact that the emissions are not permanent

5 The systolic blood pressure reading of 140-159 the systolic blood pressure reading of 140 - 159 is what stage of Hypertension?
A Stage 2
B Stage 1
C Stage 3
D High Normal
Answer:
B. Stage 1
Explanation:
Systolic blood pressure is less than 120 mm Hg and Diastolic less than 80 mm Hg so it is considered as normal. Pre-Hypertension occurs when the Systolic blood pressure is 120 - 139 and Diastolic pressure is 80 - 89. Stage 1 Hypertension is considered when the Systolic blood pressure is 140 - 159 and Diastolic blood pressure is 90- 99. If the Systolic blood pressure is greater than 160 it is considered as Stage 2 Hypertension.
how do allosteric enzymes activate and inhibit chemical reactions in a living organism?
Answer:
Allosteric activators bind to locations on an enzyme away from the active site, inducing a conformational change that increases the affinity of the enzyme's active site(s) for its substrate(s). Allosteric inhibitors modify the enzyme's active site so that substrate binding is reduced or prevented.

A polygraph test is conducted, and the findings indicate that there is an 80 percent chance of deception. What does this mean for the investigation?
The suspect is guilty and should be arrested for the crime.
The suspect is probably just nervous since 80 percent is a pretty high number and usually indicates a false positive.
The suspect might be guilty, but more information is needed from other parts of the investigation.
There has been a mistake in the polygraph test, and the test should be conducted again to get better results.
Answer:
The suspect might be guilty, but more information is needed from other parts of the investigation.
Explanation:
Due process states innocent until proven guilty. Having an 80 percent chance of deception is not solid proof of anything. It does, however, bring more speculation to the table that this person is indeed guilty, but because there is no actual proof, the investigators must find more information on the matter.

1. The arctic tundra is a tragile ecosystem. Use the pictures and descriptions in section 2 to answer the following:
Based on your observations of the ecosystem, which of the following characteristics is TRUE about the fragile tundra
ecosystem?
Answer please
This question is incomplete because the images a section 2 are not given. I searched for the complete question but could not find it. However, based on my knowledge and the characteristics of the tundra this is the answer.
The correct answer is C. The climate is harsh, which limits the number of species that can live there.
Explanation
The tundra is the name of an ecosystem that occupies a fifth of the earth's surface, mainly in the northern hemisphere, this is characterized by having a frozen subsoil that limits the emergence and growth of natural vegetation and trees. This ecosystem is the coldest on the planet due to its location near the poles, its landscape is characterized by a layer of snow that covers most of the ground. In addition, the climatic conditions are extreme, which limits the number of plant and animal species that can live there. According to the above, the correct answer is C. The climate is harsh, which limits the number of species that can live there.
¿De qué manera pueden complementarse la
teoría Sintética y la teoría de los Equilibrios
Puntuados?
La teoría sintética
El redescubrimiento en 1900 de la teoría de la herencia de Mendel por el botánico y genetista holandés Hugo de Vries y otros llevó a un énfasis en el papel de la herencia en la evolución. De Vries propuso una nueva teoría de la evolución conocida como mutacionismo, que esencialmente eliminó la selección natural como un proceso evolutivo importante. Según de Vries (a quien se unieron otros genetistas como William Bateson en Inglaterra), en los organismos tienen lugar dos tipos de variación. Una es la variabilidad "ordinaria" observada entre los individuos de una especie, que no tiene consecuencias duraderas en la evolución porque, según de Vries, no podría "conducir a una transgresión de la frontera de la especie [es decir, al establecimiento de nuevas especies] incluso en las condiciones de la selección más rigurosa y continua ". El otro consiste en los cambios provocados por mutaciones, alteraciones espontáneas de genes que dan lugar a grandes modificaciones del organismo y dan lugar a nuevas especies: “La nueva especie se origina así de repente; es producido por el existente sin ninguna preparación visible y sin transición ”.
Muchos naturalistas se opusieron al mutacionismo y, en particular, los llamados biometristas, liderados por el estadístico inglés Karl Pearson, quien defendió la selección natural darwiniana como la principal causa de la evolución a través de los efectos acumulativos de variaciones individuales pequeñas y continuas (que los biometristas se supone que pasa de una generación a la siguiente sin estar limitado por las leyes de herencia de Mendel).

Compare and contrast the cell cycle with mitosis and the cell cycle with meiosis. Citing atleast 4 similarities and 5 differences.
Answer:
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. Chromosomes replicated during the S phase are divided in such a way as to ensure that each daughter cell receives a copy of every chromosome. In actively dividing animal cells, the whole process takes about one hour.
Meiosis is the form of eukaryotic cell division that produces haploid sex cells or gametes (which contain a single copy of each chromosome) from diploid cells (which contain two copies of each chromosome). The process takes the form of one DNA replication followed by two successive nuclear and cellular divisions (Meiosis I and Meiosis II). As in mitosis, meiosis is preceded by a process of DNA replication that converts each chromosome into two sister chromatids.
Diminished bone mineral density can result from inactivity. In contrast _______________ can stop if not reverse the loss of bone mineral density.
Answer: Resistance exercise
Explanation:
A decrease in the quantity of mineral in the bone can occur due to inactivity or less body movements which may be as a result of old age or a disease condition.
RESISTANCE EXERCISE is a type of training in which the muscles are subjected to work against a weight to help increase the strength of the muscles. Below are the different forms of resistance exercise:
--> Resistance bands: these bands provides resistance when they are stretched.
--> Suspension equipment: this training tool uses the body weight and gravity to form resistance.
--> Your own body weight: one can conveniently use the body weight for push ups and squats.
Generally, the resistance exercise helps to reverse the loss of bone mineral density through increasing muscle strength and tone and reducing inactivity in the muscles that led to diminished bone mineral density.
