Identify the biotic limiting factor from the choices below.. a.space. b.vegetation. c.water. d.climate

Digiron [165]

Limiting factors are what controls the population of an ecosystem. It also limits the kind of organisms that inhabit it. Limiting factors can be abiotic or biotic. Abiotic factors are the nonliving factors that affect the living ones. From the given options above, the only biotic limiting factor is vegetation. The correct answer would be option B.

Many drugs that reach the developing fetus or embryo can cause death or congenital defects. what are examples of congenital defe

geniusboy [140]

• Skeletal and limb abnormalities

• Central nervous system alterations

• Heart defects

These are applicable in examples to many drugs that reach the developing fetus or embryo can cause death or congenital defects.

<h3>What is meant by congenital defects?</h3>

A congenital anomaly is a morphological or functional abnormality that appears during intrauterine life.
These illnesses, which are also known as birth defects, congenital disorders, or congenital abnormalities, arise during pregnancy and can be detected before or at birth as well as later in life.

<h3>What kinds of flaws are instances of congenital?</h3>

Cleft lip and palate are typically discovered during standard prenatal screenings.
congenital heart disease, which might include a hole in the heart, a valve issue, or a blood vessel issue.
Usually identified in the first few years of life, cerebral palsy.

<h3>Each of the medications or drug classes listed below has the potential to give birth to abnormalities in an unborn child:</h3>

ACE inhibitors (angiotensin converting enzyme).
antagonist of angiotensin II.
alcohol
cocaine
isotretinoin (an acne medication) (an acne drug)
high vitamin A dosages.

lithium.

Describe the process of light-independent

xxTIMURxx [149]

Explanation:

Light energy is absorbed and transferred to the reaction center.
A water molecule is split.
Electrons are transferred from photosystem II to photosystem I.
ATP is synthesized from ADP and inorganic phosphate.

Output: ATP, NADPH, O2

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

The chloroplast is a membrane bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.

During the light reaction:

Light is absorbed by pigments in phosystem II (PSII). This energy is transferred among pigments til it gets to the reaction center, and is transferred to P680; this promotes an electron to a higher energy level where it then goes to an acceptor molecule.
Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent.
the electron moves down an electron transport chain (to PS I)where it experiences continuous energy loss. This energy fuels the pumping of H+ from the stroma to thykaloid, leading to the formation of a gradient. The H+ move along their gradient and cross through ATP synthase, into the the stroma.
ATP synthase converts ADP and Pi to the energy storage molecule ATP.
The electron gets to photosystem I where it goes to pigments at P700. It absorbs light energy, the electron is promoted to a higher energy level, and passed to an electron acceptor. This leaves a space for another electron which is then replaced by one from photosystem II.
in the ETC, the molecule NADP is reduced to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.
