as we all know that photosynthesis require sunlight so it only occur in day time. so ultimately option A

Phloem transports food materials from the leaves to different parts of the plant. The transportation of food in phloem is achieved by utilizing energy from ATP which helps in creating osmotic pressure that transport food from the area of high concentration to low concentration.

Water and minerals are transported from roots upwards through xylem tissue whereas food is transported from leaves and storage organs to other parts of the plant through phloem tissue. Food is transported in both directions.

carbo- a combining form used in the names of chemical compounds in which carbon is present: carbohydrate.

Fishes absorb oxygen from water through gills

fishes have gills to absorb oxygen

Golgi apparatus plays the important role of packaging various substances for further use or for storage. If there was no Golgi apparatus, various substances would not be in a position to be transformed in proper forms for further use. Certain substances; like protein and lipid are important for the formation of plasma membrane and hence absence of Golgi apparatus will hamper the formation of new cells during cell division.

The plant wl die due to lack of sunlight and inability to conduct photosynthesis.

Thesubstances like CO2 and water move in and outof acellby diffusion from the region of high concentration to low concentration. When the concentration ofCO2 and wateris higher in external environment than that inside thecell,CO2 and water movesinside thecell

Kidney stones (renal lithiasis, nephrolithiasis) are hard deposits made of minerals and salts that form inside your kidneys.

Kidney stones have many causes and can affect any part of your urinary tract — from your kidneys to your bladder. Often, stones form when the urine becomes concentrated, allowing minerals to crystallize and stick together.

Ans :- The kidneys perform many crucial functions, including:

maintaining overall fluid balance.

regulating and filtering minerals from blood.

filtering waste materials from food, medications, and toxic substances.

creating hormones that help produce red blood cells, promote bone health, and regulate blood pressure.

nephron is the excretory unit of kidney

Nephron is the excretion unit of a kidney

I was not told about food I told about function of kidney

Their basic functions include:

Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.

Regulation of osmolarity.

Regulation of ion concentrations.

Regulation of pH.

Excretion of wastes and toxins.

Production of hormones.

The constancy is maintained because the cells in all these three structures undergo only mitotic divisions.

Explanation:The parents are diploid (2n) as each of them has two sets of chromosomes. They form haploid (1n) male and female gametes through the process of meiosis. The haploid gametes have one set of chromosomes. Since these two gametes fuse during fertilisation, the original number of chromosomes is restored in the offspring.

Haemophilia is associated with X chromosome.

Chromosomes are string-like structures located inside the nucleus of animal and plant cells.

In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of theX chromosome, while males have one X and oneY chromosome.

1 pair of chromosome are sex chromosomes

Ans :- This is because the cells of theorganismhave specialized into manydifferent typesof cells such as nerve cells, blood cells, muscle cells all performingdifferentfunctions.

The basic essential activities performed by an organism to withstand its life are called as life processes. These include nutrition, respiration, circulation, excretion and reproduction. Organisms obtain energy from food to perform these life processes which are essential for survival.

There are seven life processes that tell us that animals are alive. To help us remember them we have found a friend to remind you - Mrs Nerg. Although her name sounds a bit strange, the letters in it stand for the life processes - movement, reproduction, sensitivity, nutrition, excretion, respiration and growth.

nice answer.............

a process by which living things produce energy from food. Respiration usually needs oxygen

The physiological definition of respiration differs from the biochemical definition, which refers to a metabolic process by which an organism obtains energy (in the form ofATP) byoxidizingnutrients and releasing waste products. Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns thediffusionand transport of metabolites between the organism and the external environment.

The basic essential activities performed by an organism to withstand itslifeare called aslife processes. These include nutrition, respiration, circulation, excretion and reproduction. Organisms obtain energy from food to perform theselife processeswhich are essential for survival.

The process which maintain body functions and are necessary for survival are called life processes

1. Don't throw waste in water bodies.

2. Industry should not allowed to dispose chemical waste in water bodies.

3. Proper sewage treatment and management.

Various functions carried out by living beings; which are necessary to maintain and continue life are called life process.

Following are the life processes in living beings:

The functional elements of solid waste management are as follows:

Waste generation:Those activities in which materials are identified as no longer being of value and are either thrown away or gathered for disposal.

Onsite handling, storage and processing:Those activities associated with the handling, storage and processing of solid waste wastes at or near the point of generation.

Collection:Those activities associated with the gathering of solid wastes and the hauling wastes after collection to the location where the collection vehicle is emptied.

Transfer and transport:Those activities associated with the transfer of wastes from the smaller collection vehicle to the larger transport equipment and the subsequent transport of the wastes, usually over long distance to the disposal site.

Processing and recovery:Those techniques, equipments and facilities used both to improve the efficiency of the other functional elements and to recover usable materials, conversion products or energy from solid wastes.

Disposal:Those activities associated with ultimate disposal of solid wastes including those waste collected and transported directly to the landfill site, semisolid waste from waste water treatment plants, incinerator residue, compost or other substances from various solid waste processing plants that are of no further use

The age of fossils is determined through relative dating, and objective dating.

Fossils themselves usually can’t be directly dated, because most of them have little or no of the organic material left, and dating by Carbon 14 is only useful up to around 35000–50000 years. Fossils older than that must be dated by the rock layer in which they are found.

Fortunately, scientists have been studying rock strata for over 300 years, and have worked out very precisely the order in which the rock layers have been laid down. Very roughly, rocks are ranked in eras from oldest to youngest:

PreCambrian, Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, Paleogene, Neogene. Throughout the world, rocks are always found in this order, unless there’s been some obvious disturbance. This allows scientists to place a fossil found within a particular rock layer within these particular age brackets.

The only problem with this, is that knowing which layer is older than the next doesn’t give us an objective date for the rock layer. We can only know, from the above, that a cretaceous fossil is younger than a Jurassic one.

2)Brassica oleracea is the scientific name of 'wild cabbage'. By artificial selection many other species like Brussels sprout, Kohlrabi, Kale, Broccoli, Cabbage, Cauliflower have been produced form this.

As per your question

1) In case of cabbage the selected feature is 'terminal buds'.

2) In case of cauliflower the selected feature is 'flower clusters'.

Artificial selection helps to produce organisms with desired trait or combination of traits.This method also explains us that different looking structures can evolve from the same origin. For example, different vegetables are evolved from wild cabbage. Some farmers wanted to select for very short distances between leaves, and have bred the cabbage we eat. Some wanted to select for arrested flower development, and have bred broccoli, or for sterile flowers, and have made the cauliflower. Some have selected for swollen parts, and come up with kohlrabi. Some have simply looked for slightly larger leaves and come up with a leafy vegetable called kale. So, cabbage, cauliflower, broccoli, kohlrabi and kale are descended from the same ancestor, wild cabbage by artificial selection.

Propionibacterium sharmani

Thyroxineis the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys.Option D

answer b) protein

All of the physical and chemical activities in your body that convert or use energy are calledmetabolism. These include things like breathing, digesting food, and circulating blood.

But metabolism is a pretty broad term, and it includesallof the chemical activities in your body. We can think of metabolism in two separate forms: catabolism and anabolism.Catabolisminvolves all of the metabolic processes that tear down biomolecules, whileanabolismis all of the metabolic processes that build biomolecules.

Oxygenenters the blood from the lungs andcarbon dioxideis expelled out of the blood into the lungs. The blood serves totransportboth gases.Oxygeniscarriedto the cells.Carbon dioxideiscarriedaway from the cells.

Jaundice is a sign of abnormal bilirubin metabolism and excretion.

Excretion is a process by which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. Excretion is an essential process in all forms of life. For example, in mammals urine is expelled through the urethra, which is part of the excretory system.

The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body.
