The following is a growth curve of bacteria. What type of growth curve is pictured? A) linear growth B) logistic growth C) exponential growth
Answer:
C) exponential growth
In the given figure, exponential growth curve is pictured.
What is exponential growth?It is the pattern of data, which demonstrates greater enhancements with passing time, giving rise to a curve of an exponential function. During the growth cycle of bacteria, the cells of bacteria goes through different phases, that is:
Lag phaseExponential phaseStationary phaseDeath phaseIn the case of bacteria, the cells enter the log or the exponential phase after the lag phase. This is the time when the cells get differentiate by the process of binary fission and double in numbers after each generation time.
In this pattern of growth, the metabolic activity is high as RNA, DNA, the components of the cell wall, and other substances essential for growth are generated for differentiation.
Thus, the pattern of growth demonstrated in the given figure is exponential growth.

A Folded mountain
B Ocean trench
C Mid-ocean ridge
D Fault
Answer:
folded mountain
hope it will help you
The crustal feature is most likely found between the South American and African plates is folded mountain. The correct option is A.
What is folded mountain?When two or more of the tectonic plates of Earth are forced together, fold mountains are formed.
Rocks and debris are bent and folded into rocky outcrops, hills, mountains, and entire mountain ranges at these interacting, compressing limits. Orogeny, a process, is what produces fold mountains.
While having a narrower width than their length, fold mountains are very long.
Concave and convex slopes are typically present on opposite sides of fold mountains. Most fold mountains are located on the edges of continents that face the ocean.
A student created a chart to categorize plates according to the different boundary types. The folded mountain is most likely the crustal feature that lies between the South American and African plates.
Thus, the correct option is A.

Various factors influences the fluidity of the phospholipid bilayer of the cell membrane. If we were to chart the composition of cell
membranes in organisms as we move north from the equator to higher latitudes around the Arctic circle, we would expect to find
phospholipids with

fewer hydrophilic heads.
B)
fewer interspersed cholesterol molecules.
both saturated and unsaturated fatty acid tails.
D
an increase in the length of the fatty acid tails.
Answer:
D
an increase in the length of the fatty acid tails.
Explanation:
As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated
and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and
decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and
more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity

humans?
A)malaria and ebola
B)sickle cell anemia and malaria
C)cytochrome c disease and plasmodium fever
D)iron-deficient anemia and yellow fever
Answer:
sickle cell anemia and malaria
Explanation:
Scientists believe the sickle cell gene appeared and disappeared in the population several times, but became permanently established after a particularly vicious form of malaria jumped from animals to humans in Asia, the Middle East, and Africa.
The two diseases have been studied together that provide evidence of evolution in humans is sickle cell anemia and malaria.
What is sickle cell mutation?
The sickle cell mutation is relevant to malaria because infection of a red blood cell with the malaria parasite leads to hypoxia. In individuals of the AS genotype such blood cells sickle and are then eliminated by macrophage cells of the body’s immune system, lessening the burden of infection (Luzzatto, 2012). Carriers of the sickle cell trait are particularly resistant to severe malarial episodes; they are less resistant to mild cases. The mechanism by which carriers are protected from malaria is different than the acquired immunity that both AA and AS individuals achieve following repeated exposure to the disease.
The benefit that possessing a single copy of the sickle cell gene conveys counterbalances the biological cost incurred when homozygous SS children are stricken with sickle cell disease. An individual of the AS genotype is more likely to reach adulthood than is an individual of the AA genotype, but the former is also more likely to see his/her child die of sickle cell disease. This is known as a heterozygote advantage or balanced polymorphism. As shown more formally below, the stronger is the pressure of malaria on survival, the more advantaged are individuals who carry the S gene, and in equilibrium, the higher the percentage of the population who will be carriers. Indeed, it was the correlation of high prevalence of the sickle cell gene and the presence of malaria that first led scientists to understand the protective role of the sickle cell mutation (Kwaitkowski, 2005). As will be seen in the next section, the underlying genetic mechanism by which the sickle cell trait is transmitted provides a means of mapping sickle cell prevalence into an estimate of the mortality burden of malaria.

Two ecosystems are compared in terms of population size and species diversity. One ecosystem has a large number of individuals but low species diversity, while the other ecosystem has fewer individuals but greater species diversity due to high mutation rates. Which of the following statements best describes how these two ecosystems would respond to an environmental stress such as drought?
The ecosystem with greater diversity is less dependent upon resources and would suffer less from the drought.
The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
The ecosystem with more individuals is less likely to suffer because it is more productive and, therefore, more stable.
The ecosystem with more individuals is more likely to have members that are drought-resistant and will survive and reproduce.
Answer: I had the same problem in one of my exams. I think the answer is "the ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
Explanation:
I chose this because it seems like the most logical explanation.
"The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.
What is biodiversity?Biodiversity is considered as the variety of living things found in the various habitats, such as terrestrial, marine, and desert ones, as well as the ecological groups to which they belong.
The variety of the creatures present in an ecosystem, as well as their relative abundances, is referred to as biodiversity. It also depicts the various stages of organism organization.
In ecosystem there are thirteen different grass species present and in ecosystem Y 1 species of grass present, that is, ecosystem X has a greater amount of biodiversity. So, during the drought, the bison in ecosystem X are better able to survive.
Therefore, "The ecosystems with greater diversity is more stable and would, therefore, be more likely to withstand the drought. Thus, option B is correct.

Explanation:
Because the process of transcription takes place in nucleus so it should be put inside the nucleus.
What is nucleus?In genomics, a nucleus is a membrane-enclosed organelle within a cell that houses the chromosomes.
What is Transcription?The process in which information of a strand of DNA is copied into a new m RNA molecule is known as Transcription.
The enzyme responsible for transcription is RNA polymerase. Transcription start when RNA polymerase binds to a promoter region at the start of a gene directly or through helper proteins. Initiation, Elongation, and termination are the three steps of transcription. Transcription is carried out with the help of enzyme RNA polymerase and some proteins known as transcription factors. Enhancer and promoter sequences are the DNA sequences on which transcription factors attach to initiate the transcription process by directing RNA polymerase to the correct transcription site.The transcription initiation complex is made up of transcription factors and RNA polymerase working together.

Answer:
c increases genetic diversity
Explanation:
Answer:
C. increases genetic diversity
Explanation:
First, by process of elimination: sexual production doesn't necessarily increase survival rate, it can, but not always. Sexual reproduction involves two parents, so b is wrong. And sexual reproduction doesn't produce identical offspring, because it's mixing the genes from both parents, do d is wrong. That only leaves c, with two parents, the gene pool is always expanding, and with less chance of mutation

Answer:
D.Para la mayoría de los ecosistemas la energía proviene de la luz
Explanation:
Los ecosistemas requieren de un suministro constante de energía para poder sustentar la vida. A excepción de ecosistemas basados en fuentes hidrotermales, en general este aporte energético proviene del sol que suministra energía lumínica la cual es convertida por los organismos productores (por ej., plantas y algas) en compuestos orgánicos. Los productores representan la fuente de energía y alimento de consumidores primarios (por ejemplo, herbívoros), los cuales a su vez sirven de sustento para consumidores secundarios (por ej., carnívoros), estos suministran de alimento a los consumidores terciarios y así sucesivamente. Finalmente, los descomponedores son aquellos microorganismos que se alimentan de los restos orgánicos obtenidos a partir de productores y consumidores.
