The cell membrane is selectively permeable because substances do not pass through it indiscriminately. This means that only selective molecules pass through it. So the correct answer choice is option (B).

Selective permeability of a cell membrane refers to its ability to distinguish between different types of molecules, allowing only some molecules through while blocking others. A cell membrane is called selectively permeable because it allows only specific molecules to pass through. Only specific molecules, such as water and gas molecules, can pass directly through the cell membrane. It stops the flow of other molecules towards the two sides. Many large molecules like glucose and other sugars cannot do this. Water can pass between lipids. The most common example is the phospholipid bilayer cell membrane that surrounds every cell in our body.

Endosulfan is an organochlorine insecticide that was widely used in agriculture to control insects on various crops. However, it has been associated with several environmental and health concerns.

Studies have indeed shown that endosulfan can accumulate in the environment, including in humans. The compound is highly persistent and can remain in soil, water, and plants for an extended period. Due to its persistence, it can bioaccumulate in the food chain, with organisms at higher trophic levels accumulating higher concentrations of the chemical.

Human exposure to endosulfan can occur through various routes, including inhalation, ingestion of contaminated food and water, and dermal contact. The compound has the potential to bioaccumulate in the human body, primarily in fatty tissues. Once accumulated, endosulfan can persist for a long time, as it has a relatively long half-life.

The health effects of endosulfan in humans are a subject of concern. It is considered a potential endocrine disruptor and neurotoxicant. Prolonged exposure to high levels of endosulfan has been associated with various health problems, including reproductive disorders, developmental delays in children, and neurological issues.

In response to the environmental and health concerns associated with endosulfan, many countries have taken measures to restrict or ban its use. The Stockholm Convention on Persistent Organic Pollutants has listed endosulfan as a persistent organic pollutant, and several countries have banned or severely restricted its use.

It's important to note that the information provided is based on the knowledge available up until September 2021. Therefore, it's advisable to refer to the most recent studies and regulatory guidelines for the latest information on endosulfan and its effects on human health and the environment.

Plants require essential elements for growth. These can be divided into two types. The soil supplies relatively large amounts of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), potassium (K), sulfur (S), calcium (Ca) and, magnesium (Mg). And thus, these are called macronutrients. boron (B), chlorine (Cl), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), nickel (Ni), and zinc (Zn). In relatively small amounts, the plant also requires iron (Fe), manganese (Mn), boron (B), molybdenum (Mo), copper (Cu), zinc (Zn), chlorine (Cl), and cobalt (Co), which are called

Boron deficiency leads to the stout axis: true

Boron is involved in vegetative and reproductive cell growth. Deficiency of this nutrient is common. It is caused due to low Boron content in water or fertilizer or due to increased uptake of calcium which inhibits boron uptake. Boron deficiency leads to stunted and distorted growing tips. Therefore, the statement is correct.

B. Every mineral element that is present in a cell is needed by the cell: false

Minerals absorbed by the plants are generally utilized for their growth and development. But that is not true for all elements. Plants also absorb minerals like lead, silicon, uranium, silver, gold, etc that are not essential for growth. This phenomenon is mostly seen in plants growing near the mining areas. Thus the statement is false

C. Nitrogen is a nutrient mineral, is highly immobile in the plants: false

Minerals like nitrogen, phosphorus, potassium, magnesium, chlorine, zinc, and molybdenum are mobile nutrients in plants whereas calcium, sulfur, iron, boron, and copper are immobile nutrients. Thus the statement is false.

D. It is very easy to establish the essentiality of micronutrients because they are required only in trace quantities: false

As plants require certain nutrients in trace quantities, it is difficult to establish their essentiality. Thus the statement is false.

Note: Plants take up essential elements from the soil through their roots and from the air through their leaves. The root, especially the root hair, is the essential organ for the uptake of nutrients. Thus, any alteration in the structure and architecture of the root can affect the rate of nutrient uptake. Nutrient uptake by plants is by simple diffusion, facilitated diffusion, or active transport.

Answer:The role of wetlands in the carbon cycle

Department of Sustainability, Environment, Water, Population and Communities

Inter-tidal wetlands, such as mangroves, play an

important role in carbon sequestration.

(Shane Cridland)

Wetlands play an important role in landscape function, including cycling of carbon, water and nutrients, food and fibre production, water purification, regulation of flows, provision of habitats, and tourism and recreation services.

The role of wetlands in carbon sequestration and storage has generally been under-estimated. Wetlands cover approximately six to nine per cent of the Earth's surface and contain about 35 per cent of global terrestrial carbon. As wetlands are centres of high productivity in the landscape, they have a high capacity to sequester and store carbon. As depositional areas, wetlands can also store carbon-rich organic sediments. However, under anaerobic conditions, wetlands can also produce greenhouse gases such as methane and nitrous oxide, though this is limited in saline conditions. Clearing or drainage of wetlands can lead to large losses of stored organic carbon to atmospheric carbon dioxide.

Greater consideration needs to be given to the roles of wetlands as carbon sources, sinks and storages when designing climate protection and natural resource programs. Therefore, in consultation with the Wetlands and Waterbirds Taskforce, the Australian Government Department of Sustainability, Environment, Water, Population and Communities has developed an issues paper, The role of wetlands in the carbon cycle. This paper considers the role of wetlands in carbon cycling, the implications of climate change for wetland functions and services, and mechanisms to promote protection and restoration of wetlands for multiple benefits including carbon sequestration.

The offspring will not inherit the mutation if a woman has a mutation in one of her skin cells. Skin cells are considered somatic cells, which are body cells and not involved in the production of reproductive cells (eggs or sperm).

The inheritance of a mutation in a woman's skin cell will not impact her offspring because it does not affect the genetic material that is passed on during reproduction.

Somatic mutations occur in non-reproductive cells and are not passed on to offspring.

In sexual reproduction, the genetic material that is passed on to offspring comes from the reproductive cells. Mutations that occur in the DNA of reproductive cells, such as eggs or sperm, have the potential to be inherited by offspring. However, mutations in somatic cells, including skin cells, do not affect the genetic material in reproductive cells and are not passed on to future generations.

Answer:true

Explanation:

Type-A blood will produce Anti-B antibodies when challenged with type-B blood. The given statement is true.

When someone with type-A blood is challenged with type-B blood, they will produce Anti-B antibodies in response, as they do not have the B antigen naturally present on their own red blood cells. These antibodies will recognize the B antigen on the foreign red blood cells and bind to them, leading to the clumping and destruction of those cells.

This reaction is known as agglutination and is responsible for the adverse effects seen in transfusion reactions and hemolytic disease of the newborn.In contrast, individuals with type-B blood naturally produce Anti-A antibodies in their blood, which will recognize and bind to the A antigen on foreign red blood cells if they encounter them.

Individuals with type-AB blood have both A and B antigens present on their own red blood cells and do not produce either Anti-A or Anti-B antibodies. Finally, individuals with type-O blood do not have either A or B antigens present on their own red blood cells and therefore produce both Anti-A and Anti-B antibodies.

Explanation:

The genetic material  needed for sexual reproduction must come from both parents. The gametes, or sex cells, of the parent plants are both male and female.

To create babies, the genetic material from the male and female gametes is combined. This procedure is known as fertilization. Seeds are the result of sexual reproduction.

Genetic material from both parents is present in seeds that are created by fertilization. As a result, neither of the parent plants' offspring and the offspring are genetically similar. They may be able to survive if the environment changes thanks to their genetic variety.

Pollination, the act of sexual reproduction in flowering plants, is how it happens. Stamens, the male sex organ, and pistils, the female sex organ, are found in flowers.
