Answer:

The correct answer is - decreased population size at all levels.

Explanation:

A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.

It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.

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.

Answer:

Mammals give birth to live young, whereas the birth of amphibians takes place externally. Mammals are warm-blooded, while amphibians are cold-blooded. Mammals can live in all habitats, unlike amphibians, and have muted colors. Some amphibians can regenerate their limbs.

Answer:

The dependent variable is fermentation rate.

Explanation:

When finding dependent variable phrase it like this:

______ depends on _____.

Where the first blank is the dependent variable and the second blank is the independent variable. For example, if I were to test the effects of pH on an enzyme, I would say the function of the enzyme depends on the pH level. This makes the function of the enzyme the dependent variable. In this case, fermentation rate depends on the different sugars. Hope this helps!

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).

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.

Answer: April Cashin-Garbutt, MA, reviewed it (Cantab) Collagen is a protein composed up of amino acids, which are carbon, oxygen, and hydrogen molecules. Glycine, Proline, Hydroxyproline, and Arginine are among the amino acids found in collagen. Collagen makes up around a third of the proteins in the human body.

Explanation:

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

Answer:

The left ventricle cannot pump enough blood to meet the body's demands

Explanation:

Cardiogenic shock is a problem that occurs when the heart cannot pump the adequate amount of blood to supply all organs. In this situation, the left ventricle, responsible for pumping oxygen-rich blood, cannot pump enough blood to tend the body's demands. This causes blood pressure to drop and oxygen in the tissues to be lacking. In addition, this situation can cause accumulation of fluid in the lungs. This is a very dangerous problem, being one of the main causes of myocardial infarction.

Answer:

The biology term, haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes

The term used to describe the number of chromosomes in a gamete would be haploid.

Gametes are usually formed by meiosis and meiosis is referred to as reductional division. When a normal diploid (2n) cell divides by meiosis, the daughter cells would have half the number of chromosomes of the parent cell. In other words, the daughter cells will have n number of chromosomes as opposed to 2n.

Cells with n chromosome numbers are generally referred to as haploid while those with normal 2n chromosome numbers are said to be diploid. Egg and sperm cells are haploid cells.

Answer: yes it is correct

Explanation:

Hope this helps you with your science 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.

Answer:

A. Prokaryotic cells

Explanation:

Prokaryotic cells don't have organelles

Answer:

1-Meiosis:  

- Independent assortment: Anaphase I

- Segregation: Anaphase II

2-Mitosis  

- Segregation: Anaphase  

Explanation:

The Principle of Independent Assortment described by Mendel indicates the mechanism by which different genes get sorted into gametes (i.e., eggs and sperms in mammals) independently of one another, while the Principle of Segregation indicates the mechanism by which gene variants (i.e., alleles) segregate (separate) into gamete cells. In eukaryotic organisms, independent assortment occurs during anaphase I of meiosis, when each pair of homologous chromosomes separate. The assortment of homologous chromosomes during anaphase I explain how genes on different chromosome pairs will segregate independently of one another. On the other hand, the separation (segregation) of sister chromatids occurs in Anaphase II, where gametes carrying single gene variants (i.e., alleles) for each locus are generated.

Answer:

3. Metaphase

Explanation:

Metaphase is the stage in the cell cycle where the chromosomes line up in a line down the middle of the cell (some people call it the metaphase plate).

The way I like to remember it is: Metaphase is in the Middle.

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.
