Question Completion with Options:

a. increasing the size of your cohorts.

b. increasing the diversity of your cohorts.

c. increasing the size of your affected cohort.

d. increasing the diversity of your affected cohort.

Answer:

All of the following modifications to the study are likely to allow identification of new variants associated with the disease, EXCEPT

a. increasing the size of your cohorts.

Explanation:

Option A is chosen because increasing the size of the cohorts will be equally divided between the affected and unaffected cohorts since the study discovered that these two classes are roughly the same size.  Therefore, new variants of the disease may not likely be identified and isolated unless the other modification options are followed instead of Option A.

Answer:

The pollutants like heavy metals, organic solvents present in pesticides exist in small amounts in the atmosphere. During the process of the food chain, the concentration of these pollutants progressively keeps on increasing through different trophic levels. For example, fish eats a lot of planktonic growth may retain the pollutants in their tissues, birds or people that eat the fish might concentrate the pollutants still more. This process of accumulation of pollutants at different trophic levels is called as biomagnification. So, the correct answer is 'Assertion is correct but Reason is incorrect'.

Answer:

Addaptational changes since they had to adjust to a new environment

The color change of the peppered moths from light to dark after the Industrial Revolution Adaptational changes since they had to adjust to a new environment.

During the industrial revolution, the color of bark of the trees became dark. Due to this the predators could easily detect the light colored moths on the dark colored bark of the trees.  

This lead to evolution of light colored moth resulting into dark colored moths through the process of natural selection which made the newly evolved moth population more prominent to the predation attack.  

It became difficult for the predators to trace moth on the tree barks as they became capable of camouflaging against the color of  bark.

Thus, adaptation is the main reason.

Answer:

Dissimilatory- oxygen absent

Assimilatory- high concentration of nitrite

Explanation:

In assimilatory nitrate reduction, ammonium is produced and subsequently incorporated into biomass to build up e.g., proteins and nucleic acids. Dissimilatory nitrate reduction is a process for energy conservation, in which nitrate is used as an electron acceptor in the (near) absence of oxygen . Dissimilatory nitrate reduction and nitrate storage in particular are physiological life traits that provide microbes with environmental flexibility (i.e., metabolic activity under both oxic and anoxic conditions) and resource independence (i.e., anaerobic metabolism without immediate nitrate supply), respectively. Such life traits are especially important in environments that are temporarily anoxic and/or nitrate-free and they may have developed as a “life strategy” in both prokaryotes and eukaryotes

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.

Conifer Leaf.  

Microphyll Leaf.  

Megaphyll Leaf.

A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.

The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

Answer:

Explanation:

Step 1: Generating a Proton Motive Force

The hydrogen carriers (NADH and FADH2) are oxidised and release high energy electrons and protons

The electrons are transferred to the electron transport chain, which consists of several transmembrane carrier proteins

As electrons pass through the chain, they lose energy – which is used by the chain to pump protons (H+ ions) from the matrix

The accumulation of H+ ions within the intermembrane space creates an electrochemical gradient (or a proton motive force)

Step Two: ATP Synthesis via Chemiosmosis

The proton motive force will cause H+ ions to move down their electrochemical gradient and diffuse back into matrix

This diffusion of protons is called chemiosmosis and is facilitated by the transmembrane enzyme ATP synthase

As the H+ ions move through ATP synthase they trigger the molecular rotation of the enzyme, synthesising ATP

Step Three: Reduction of Oxygen

In order for the electron transport chain to continue functioning, the de-energised electrons must be removed

Oxygen acts as the final electron acceptor, removing the de-energised electrons to prevent the chain from becoming blocked

Oxygen also binds with free protons in the matrix to form water – removing matrix protons maintains the hydrogen gradient

In the absence of oxygen, hydrogen carriers cannot transfer energised electrons to the chain and ATP production is halted

Answer: Fertilization occurs, a zygote undergoes mitosis, a baby's cells divide mitotically, meiosis produces sex cells that will participate in fertilization.

Explanation:

Incomplete questions, options are:

Meiotic cell division occurs as the zygote develops into a gamete, meiosis produce the sex cells that will participate in fertilization, a baby grows into an adult through uncountable meiotic divisions, fertilization occurs, a zygote undergoes mitosis, a baby's cells divide mitotically, mitosis produces gametes.

1. Fertilization occurs: Fertilization is the union of a human egg and sperm (male and female gametes), which usually occurs in the fallopian tube. The result is the formation of a zygote or fertilized egg, which initiates the development of the embryo. In this way, the genetic material of both gametes is also fused.

2. A zygote undergoes mitosis: The zygote is the union of the egg and the sperm. Each gamete contributes 23 chromosomes to form the genetic material of the future organism. The zygote starts to divide throught mitosis. Mitosis is a type of cell division that generates two genetically identical daughter cells and occurs in somatic cells (all cells in the body that are not gametes). Eventually, it divides into two blastomeres, then into 4, then into 8, and so on during the passage of the zygote along the fallopian tube towards the uterus. Subsequent divisions of the 12 cells give rise to the morula. Then, the blastocyst is generated, which is an embryo of between 5-7 days of development and is composed of a large number of cells that begin to differentiate.

3. A baby's cells divide mitotically: An embryo is a living being in the early stages of its development, from fertilization until the organism acquires the morphological characteristics of the species. In the specific case of the human being, the term applies until the eighth week after conception (fertilization). Cell divisions for development occur by mitosis. In this way, the embryo will grow and develop, forming tissues and organs through growth thanks to mitotic divisions.

4. Meiosis produces sex cells that will participate in fertilization: Meiosis is a type of cell division that occurs in the gonads for the production of gametes, whereby a diploid cell undergoes two cell divisions, that generates four haploid cells. Thus sperm and oocytes are produced to eventually fuse during reproduction to form a diploid zygote. Meiosis has certain differences from mitosis, since in this type of cell division, the daughter cells created are all genetically distinct from each other and from the parent cell. This is because a crossing over occurs between non-sister chromatids of homologous chromosomes to exchange genetic material. This ensures that each gamete produced has genetic variability.

Answer:

Postural development

Explanation:

The agonist muscles are sets of muscles responsible for causing joint motion, whereas antagonist muscles are muscles that directly opposite agonist muscles (i.e., antagonist muscles generate an opposing joint torque to the agonist muscles). In a given movement, agonist muscles exhibit concentric contractions while antagonist muscles show eccentric contractions in order to stabilize the joint. Postural development is achieved by concerted adjustments of dorsal muscles and ventral muscles. The dorsal muscles are activated when the body sways forward and the muscle fascicles shorten. During backward sway, these muscles lengthen, while ventral muscles are primarily activated.

Dynamic balance is the condition that requires constant agonist-antagonist muscle contractions.

The agonist-antagonist muscle contraction is the movement where one muscle contracts while the other muscle is relaxing or lengthening. The muscle contracts are agonist whereas the muscle that relaxes is the antagonist here.

Thus, the correct answer is - Dynamic balance.

Answer:

The phase that not all cells enter, but is a phase where cells are not actively dividing is called the G0 or non-dividing phase.

Answer:

G₀ phase

Explanation:

Some types of cells divided slowly or not at all. These cells may exit the G₁ phase and enter a resting phase called G₀ phase. In G₀ phase, a cell is not actively preparing to divide. It's simply doing its job. For some cells, G₀ is a permanent state, while others may restart cell division given the right signals.
