The spicules of sponges are made up of caco3 (non living ) but why they have endo skeleton?While endoskeleton is living
Answer: The spicules of the sponges are made up of calcium carbonate and silica. These structures are present in the body of sponges to provide them support and protection.
The sponges have the endoskeleton in the body which is developed by the specialized cells of the body.
The endoskeleton of the sponges are known as spicules. Actually the outer body of the sponges are very soft and internally has endoskeleton for protection which is a bit hard as it is made of silicon dioxide or calcium carbonate.

HELP PLEASE Sucrase, lactase, and maltase break down disaccharides into monosaccharides. Monosaccharides are transported to the bloodstream. Salivary amylase breaks down carbohydrates into disaccharides. Pancreatic amylase breaks down carbohydrates into disaccharides. ↓ ↓ ↓
Explanation:
In the given question, the digestion of monosaccharides has been discussed and the steps of digestion in the digestive system are:
1. The digestion of carbohydrates begins in the mouth where amylase breaks down the starch.
2. The sugars are not completely digested in the mouth therefore they travel from mouth to the stomach.
3. In the stomach, there are no enzymes to digest the sugars.
4. Then, food enters the intestine where intestinal secretions breakdown the sugars.
5. The intestinal juice breaks down the oligosaccharides into diassacharides and these disaccharides are further broken down by maltase, sucrase and lactase.
6. After this, the monosaccharides are formed and these are easily absorbed into the bloodstream.
7. Pancreatic amylase breaks down starch into monosaccharides.
This completes the digestion of the carbohydrates.
¿Qué se entiende por homeostasis?¿Por qué es importante que las condiciones internas permanezcan dentro de un rango constante? ¿Qué ocurre si esto último no se cumple?
Answer:
La respuestas correctas son descritas en la sección de explicación
Explanation:
Homeostasis se define como un estado de relativa estabilidad dentro del medio interno de un organismo, teniendo composición y propiedades definidas dentro de un rango, las cuales deben ser cumplidas para asegurar el correcto funcionamiento del medio interno. Es precisamente el asegurar el correcto funcionamiento lo que hace importante que las condiciones internas permanezcan dentro de un rango constante. Por ejemplo, si la concentración de iones en la sangre es elevada las células pueden deshidratarse y encogerse hasta morir; o bien si la concentración de iones es baja las células pueden hincharse hasta explotar.

Red-flowered snapdragons are crossed with white-flowered snapdragons, producing all pink snapdragons in the F1 generation. What would you expect if you crossed pink with pink? The choices are... (1/2, 1/4, 3/4) red, (1/2, 1/4, 3/4) pink, (1/2, 1/4, 3/4) white.
Answer:
Red (1/4), Pink (1/2), white (1/4)
Explanation:
This question involves a single gene coding for flower colour in the snapdragon plants. The gene exhibits incomplete dominance, because the allele for red color (R) is incompletely dominant over the allele for white color (W), hence an intermediate phenotype is produced as pink color (RW).
The pink colored snapdragon plant is produced in the F1 generation. When these F1 offsprings are crossed i.e. RW (pink) × RW (pink), gametes with R and W alleles are produced by each F1 parent.
Using these gametes in a punnet square (see attached image), four possible offsprings with genotypes; RR, RW, RW and WW will be produced in the F2 generation.
RR offsprings (1/4)- Red flowered
RW offsprings (2/4 or 1/2)- Pink flowered
WW offsprings (1/4)- White flowered

a. soups - chemical synaptic transmission
b. sparks - chemical synaptic transmission
c. soups - direct electrical communication
d. sparks - direct electrical communication
Answer: Option A and D.
Soups chemical synaptic transmission.
Sparks direct electrical transmission.
Explanation:
Intercellular communication refers to the communication and interaction that exists between two cells in the body. It could be hormonal or synaptic transmission.
Synapse is the site where electric nerve impulses are transmitted between two nerve impulses.
There are two synapse possibilities which are electrical and chemical.
The Sparks and soups mean that the scientific discovery over the transmission of nerve impulses as to whether they are electrical impulses (Sparks) or chemical impulses(soup).
Chemical synaptic transmission means there is no physical touch in the space chemical are released and move to the neighbouring cells.
Electrical transmission means neuron physically touch and give way for flow of impulses between cells.
why is not recommended to use antibiotics often
Answer: It may cause the bacteria to become resistant to them and one they are resistant then the antibiotics are ineffective against the bacteria. It is then more dangerous since new antibiotics will need time.
Explanation:
Explanation:
If you take antibiotics for the wrong reason(s) or if you take them too often it can change bacteria so much, that antibiotics have a reduced effectiveness against them, or stop working against them all together.
The so called "bacterial resistance" or "antibiotic resistance" is a real thread to humans. Some bacteria have turned out to be resistant to even the most powerful antibiotics available. Antibiotic resistance is a growing problem.
Suppose you get infected with such resident bacteria, it means there is no longer an effective treatment by using antibiotics.
*EXTRA*
If left "un treated", the bacteria can grow, more or less, with unlimited exponential growth. In such scenarios, any "simple" bacterial infection, could turn out to be fatal.
Often the biggest problem is the lack of time to find out exactly what type of bacteria is making the patient ill. Because there are so many different bacteria, it is impossible to tell what is the right one without deduction and, that takes time (to grow visible cultures in the laboratory). Sometimes a patient might be already critically ill, in such cases, the doctor would want to start the treatment immediately, which could mean they HAVE TO start admitting a broad-spectrum antibiotic, to hopefully battle that group of different bacteria, which hopefully included the one that is making the patient ill. But if that specific bacteria turns out to be resestant, then that poses a very serious problem. Possible a fatal one, since the time is up, and the bacteria keep growing in numbers, roughly doubling in numbers every hour...

Ramu wants to practice crop rotation in his field. Suggest a Rabi crop and a Kharif crop, which will replenish his field with nitrogen. Which crop replenishes nitrogen and why?
Answer:
Explanation:
is a practice that involves the growing of different type of crop on the same piece of land. It is often practices by subsistence farming where the land space is not to big to accommodate all the crops to be grown separately.
Nitrogen are been replenished into the soil by leguminous crops. This is because they have root nodules which contains Nitrogen and it help fixes it back into the soil with the help of bacteria such as Azotobacter, nitrogen fixing bacteria. This bacteria acts on the nodules to help break down the Nitrogen into a form that can be useful by plants.
Example of kharif Crop is pea which are leguminous and can fix nitrogen back into the soil, maize, rice
Rabi example is wheat and barley.

Answer:
Genetically modified organisms or GMOs can be characterized as living beings (for example plants, creatures or microorganisms) in which the hereditary material (DNA) has been changed in a way that doesn't happen normally by mating and additionally common recombination. The innovation is regularly called "present day biotechnology" or "quality innovation", now and again likewise "recombinant DNA innovation" or "hereditary designing". It permits chosen singular qualities to be moved from one life form into another, likewise between nonrelated species. Nourishments created from or utilizing GM life forms are regularly alluded to as GM nourishments.
GM nourishments are created – and promoted – in light of the fact that there is some apparent bit of leeway either to the maker or customer of these nourishments. This is intended to convert into an item with a lower cost, more prominent advantage (regarding toughness or healthy benefit) or both. At first GM seed engineers needed their items to be acknowledged by makers and have focused on advancements that carry direct advantage to ranchers (and the food business by and large).
One of the destinations for creating plants dependent on GM life forms is to improve crop insurance. The GM crops as of now available are fundamentally focused on an expanded degree of harvest security through the presentation of obstruction against plant infections brought about by creepy crawlies or infections or through expanded resilience towards herbicides.
Resistance for insects is accomplished by consolidating into the food plant the quality for toxins creation from the bacterium Bacillus thuringiensis (Bt). This poison is presently utilized as an ordinary bug spray in agribusiness and is ok for human utilization. GM crops that inalienably produce this poison have been appeared to require lower amounts of bug sprays in explicit circumstances, for example where nuisance pressure is high. Infection obstruction is accomplished through the presentation of quality from certain infections that cause sickness in plants. Infection opposition makes plants less helpless to sicknesses brought about by such infections, bringing about higher harvest yields.
Herbicide resilience is accomplished through the presentation of a quality from a bacterium passing on protection from certain herbicides. In circumstances where weed pressure is high, the utilization of such harvests has brought about a decrease in the amount of the herbicides utilized.
