Sickle cell disease is a recessive trait which causes a deformation in red blood cells due to a mutation in the gene that codes for hemoglobin. Consider a father and a mother BOTH with the genotype Hh, where H is the normal hemoglobin gene, and h is the gene that codes for the defective hemoglobin. What percent of their children will have the genotype hh, which means they will have the full-blown disease?
Answer: Sickle cell disease is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. Hemoglobin transports oxygen from the lungs to other parts of the body. Red blood cells with normal hemoglobin (hemoglobin-A) are smooth and round and glide through blood vessels.

One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, species, ecosystems, and ecological processes play in supporting human society and a healthy biosphere. What are benefits provided by biodiversity?
Answer and Explanation:
Biodiversity composes of different species living in a certain restricted area. It is the variability of living beings in a natural environment, involving all the species on the planet and their genetic material. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species form.
Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.
Biodiversity, in equilibrium with abiotic factors, provides ecosystem services, which are important for the maintenance of all forms of life, including human beings.
Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems provide a recreational place or area to spend time and learn. They provide a spiritual/religious space, are a source of inspiration. Ecosystems are cultural patrimony and the source of scientific knowledge.

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.

The differences in the curves of the graphed data indicate that there were differences in the number of electrons produced in the three samples during the experiment. Discuss how electrons are generated in photosynthesis and why the three samples gave different transmittance results.
Solution:
Photosynthesis is a process by which green plants and vegetables prepare their food using carbon dioxide from the atmosphere, water from the soil and in the presence of sun light with the help of chlorophyll.
-- During photosynthesis process, electrons are originated from the chlorophyll and it absorbs the photons of light from the atmosphere.
-- the energies are passed inward from the pigments to pigments until they reaches the reaction center.
-- then the energy is transferred to the P680, thus boosting the electron to the high energy level.
-- this high energy electron then passes to the acceptor molecule and is replaced with the electron from the water.
-- this splitting the water releases oxygen in the atmosphere that we breathe.
-- the electron generation is proportional to the DPIP reduction light transmittance.
-- the decrease in the light availability decreases the electron quantity of the electrons which will be generated.
-- the boiling disrupts the functional structures.
In the lab, you isolate a mutant strain of bacteria in which the phosphatase that would normally dephosphorylate NtrC-P is defective. Assuming the levels of NtrB and NtrC protein remain normal (same as wild type), what is the expected phenotype of this mutant
Answer:
GlnA will be overexpressed and the cells will have more glutamine than glutamate
Explanation:
Glutamine synthetase (glnA) is an enzyme involved in nitrogen metabolism that catalyzes the amidation of glutamate to glutamine. Moreover, the phosphorylated form of the NtrC response regulator protein (NtrC~P) acts as a transcriptional activator of genes associated with nitrogen metabolism, including glnA. NtrC~P exhibits 1-an enhanced DNA binding activity (increased oligomerization on the target DNA template) and 2-ATPase activity (oligomerization of the NtrC phosphoprotein), which are fundamental features for transcriptional activation. In consequence, it is expected that a higher level of NtrC~P (due to a defective form of the phosphatase that dephosphorylates NtrC~P) leads to the overexpression of glnA, thereby increasing glutamine levels and simultaneously decreasing glutamate concentration.

Question b OT 15
Ain
force is the overall force on an object after all the forces
are added together.
Answer:
The correct answer is - Net force.
Explanation:
Adding all the forces that are applied to a particular object, body, or particle is the net force. This overall force that is applied can be calculated by a vector sum of all other forces exerted on the body.
So if two forces are applied in opposite directions to one another, they combine by subtraction whereas If one force is less than the other force, the net force is in the direction of the greater force.
how do you think a new community begins in an area?
Answer:
community means an interacting group of various species in a common location. communities exist but new community can cause due to certain pressures either favored by the environment/nature or by humans/simply animals.
Undergoing pressures can can cause for selections such as,
-stabilizing selection
-directional selection
-disruptive selection
or may also occur due to mutations (naturally or manmade) that will further cause for a genetic drift so the nature/ the environment will help/ favor for the best fitting species to survive resulting for an evolution and will build up a new community.

¿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).
