What are the functions of leaves? (Select all that apply.) PLEASE ANSWER ASAP AND GET 25 POINTS
release water vapor
absorb water and nutrients
store water and glucose
perform photosynthesis
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.

When an organism encounters nitrate in its environment, which condition will determine whether the nitrate is used in an assimilatory or dissimilatory manner?
a. low concentration or ammonia
b. low concentration of sulfate
c. oxygen present
d. low temperature
e. oxygen absent
f. high concentration of nitrite
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
Write the events of the human life cycle in the correct order, starting with what happens right after a pair of gametes comes together?
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.

There have been a number of studies indicating that schizophrenia is a complex genetic disorder. Which of the following observations are most consistent with this hypothesis?
1. Siblings of individuals with schizophrenia have an elevated risk of developing schizophrenia.
2. In monozygotic twins, if one twin has schizophrenia, it is very rare that the other is affected.
3. Malnutrition in utero and certain infections may increase risk of schizophrenia.
4. Schizophrenia follows an autosomal recessive inheritance pattern.
Answer:
1. and 4.
Explanation:
1 explains that siblings may have it since they have the same genetics and 4 explains that it is a autosomal recessive trait and follows a pattern genetically.
The Hardy-Weinberg principle is written as the equation p2 + 2pq + q2 = 1. What does prepresent?
Explanation:
Hardy-Weinberg principle can be illustrated mathematically with the equation: p2+2pq+q2 = 1, where 'p' and 'q' represent the frequencies of alleles. ... The principle behind it is that, in a population where certain conditions are met (see below), the frequency of the alleles in the gene pool will be constant.
Which of the following requires constant agonist-antagonist muscle contractions?
Core integration
Postural development
Dynamic balance
Neuromuscular strength
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.
Core integration: In such conditions, the constant movement of muscle contraction and relaxation does not require. It is a specific movement and increased stability of the movements.Postural development: continuous development and growth of postural muscles comprising the nervous systemDynamic balance: It would be the ability to balance in motion or changing positions. In this case, muscles require constant both agonist and antagonist contractionsNeuromuscular strength: motor commands according to the central nervous system to the ability to move in the nervous system, hence it does not require constant muscle movements.Thus, the correct answer is - Dynamic balance.

does tomato have thick or thin exocarp?
assertion: empty milk pouches are biodegradable Reason: they cannot be used in biogas formation
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'.
