While eating you should not laugh ar talk you may have heard this statement from your elders . Do you agree with this statement ? Give reasons for your answer
Answer:
One might believe that this statement has some truth to it. It is considered bad manners to talk while you are chewing your food. Let alone laughing (also a choking hazard). However it shouldn't be taken too seriously. Conversation on the dinner table can be fun while enjoying a meal with many other people. However conversation is done before taking a bite as talking with your mouth full is disrespectful to others and shows bad manners.

Why
are
fungi classified as heterotrophs like animals?
Answer:
Fungi is heterotypic animal because it takes its diet from its food chain like other animals.
Explanation:
Like animals fungi are also heterotrophs. Fungi use the complex compound in the form of carbon rather then fixing of carbon dioxide from the environment.
Most of the plants and some bacteria do the same things. Fungi does not fix nitrogen as well from the environment. Like other animals fungi takes other nutrients such as from diet. Some of the fungi multiply a-sexually and some fungi do have a-sexual and sexual reproduction with the alternation of generation. The fungi is used to commercial food industry to make the yeast for baking, brewing and for making cheese and wine. It is used for fermentation. It is also use in the form of enzymes and bacteria.
Explain the basic steps in the first half of photosynthesis. Describe the movement of electrons and the importance of hydrogen ions in developing a proton gradient that allows for ATP production.
Answer:
This simply refers to photolysis of water.
Explanation
Generally,two steps are involved in photosynthesis.
The light dependent stage or light reaction,(which is the first part of photosynthesis,
The light independent stage (which is the second part.)
The light independent reactions involved the trapping of sunlight by the photo systems, in the leaves,and the splitting of the water molecules by sunlight.
H20 + Sunlight → 1/2H+ +2 e- +1/2 O2.
The movement of electron can be cyclic or non cyclic photophosphorylation, In Cyclic, photo system 1 absorbs the electrons and pass these to the primary pigments in the leaves. This excited the electron in chlorophyll molecule to higher energy levels , The electron emitted from the leaves is by a process called by photoactivation The emitted electron do not return to the photosystems,rather they are pick up by the primary electron acceptors and returned to the chlorophyll molecules by electron carriers,NADP.
During this process Energy is released for ATPase synthase of ATP for phosphorylation of ADP with phosphate,
In Non-cyclic photophorylation,photosystem I and II absorbs the electrons as Z-scheme movement of electrons.,Photoactivation of chlorophyll takes place as in the Cyclic.The primary electron acceptors takes the excited electrons to move along the chain of electron carriers.This makes the photosystems positively charged.
Hence to regain stability the primary pigment of photo system 1 takes electrons from photosystem II.To replace its lost electrons, P II takes electrons from the photolysis of water.ATP is generated as the carriers molecules transport electrons from the energy produced.
The hydrogen ions is used for the production of electrochemical gradients,which supplies the energy used by the ATPase synthase for the ATPs production.The process is called chemiosmosis. It involved the transports of H atoms by NADPH into the stroma,and the splitting of these into protons and electrons,The electrons form ETC,which forms the PMF.The latter pumped protons into the thylakoid membrane,and as this returns it generate the electrochemical gradient.
The ATP is used in the Calvin Cycle for CHO,proteins productions,

Question 17 of 25
Why do plants produce more carbon dioxide than oxygen during the night?
A. Respiration can only occur when there is no available sunlight.
Ο Ο Ο
B. Photosynthesis only produces carbon dioxide during the night.
C. Respiration can happen without sunlight, but photosynthesis
cannot.
D. Respiration produces oxygen during the day and carbon dioxide at
night
SUBMIT
Answer:
C. Respiration can happen without sunlight, but photosynthesis
cannot.
Explanation:
Respiration is the metabolic process by which the cells of living organisms, plants inclusive, obtain energy. Photosynthesis, on the other hand, is the process whereby plant cells synthesize their food in form of sugars (glucose).
Photosynthesis takes place in two stages namely: light dependent stage and light independent stage. The light dependent stage occurs strictly in the presence of sunlight, where oxygen gas is released as a product. Hence, it can only occurs during the day. Respiration, which breaks down the sugar product of photosynthesis to produce energy, occurs at anytime (day or night). Carbon dioxide (CO2) gas is released as a product.
Since the light dependent stage of photosynthesis cannot occur without sunlight, it cannot occur at night. this means that oxygen gas will not be released at night. However, respiration which occurs during daytime and nighttime continually releases carbon dioxide gas. This accounts for the reason CO2 gas is produced more by plants than oxygen at night.

Explanation:
Assume that the point mutation and deletion mutation are not in overlapping regions of the phage genome. What phage recombinants would you expect if a crossing-over event occurred between the regions of the two mutations?
Answer:
A recombinant phage containing both mutations.
Explanation:
A recombinant organism is produced by recombination, which is a genetic phenomenon associated with the repair of double-strand breaks in DNA. In genetic research, recombinant organisms are used to investigate target gene expression. The process of DNA repair may be associated with two different pathways: homologous recombination (HR) and non-homologous end-joining (NHEJ). In this case, the recombinant phage contains no overlapping mutations (i.e., both deletion and point mutations), thereby carrying the desired genetic combination.
2. Introduce one of the four new rat species to another island and describe one challenge it would encounter and one success as it adapts to its new environment.
Answer:
Challenge : Competition form other species.
Success : Adaptation and colonisation.
Explanation:
Challenges like adapting to the new environment and different climatic zones and handle other potential threats like predators as snakes, birds, and others. Their potential to find food and sustain themselves will be a challenge. Success factors include their ability to adapt and develop a sense of the different environment and through genetic mutation and natural selection they can develop and grow in numbers.When the teacher was handing out this test, you noticed that your respiration rate and heartbeat increased, your palms got sweaty, and your hand shook a little.

identify the sphere wher life first emerged on earth hydrosphere, lithosphere, atmossphere
Answer:
hydroshere
Explanation:
hydro=water
Answer:
you're answer would be hydrosphere
Explanation:
Life on Earth, emerged in the hydrosphere, at least from the findings and data so far. The reason for that was that the atmosphere and the lithosphere were still in a faze were they were not very hospitable for any living organisms to develop. The hydrosphere, or the water bodies, on the other side, were enabling conditions for life, not perfect or as we have today, but still reasonably good, so the life started developing into the water environment, and after the atmosphere and lithosphere changed over time, it spread on them as well.

The graphic below shows how photosynthesis and cellular respiration are related.
Answer:
Humans and animals both are depend on the cellular respiration. When o2 is released by plant is inhaled by animals and humans and exhale carbon dioxide.
Explanation:
Oxygen is stored during photosynthesis and produce oxygen in cellular respiration. Carbon dioxide and water are used in photosynthesis released cellular respiration. The energy that is releases during photosynthesis is stored by the process of cellular respiration. Glucose is broken down during the process of photosynthesis, to produce the food in cellular respiration.
The relationship shows that both are reactant to each other. The photosynthesis used sunlight , water and carbon dioxide to produce the glucose. The cellular respiration used that oxygen and water to produce carbon dioxide.

In the late 1870s, Charles Darwin and his son Francis discovered that if the tip of the grass was covered, phototropism did not occur, even though the rest of the grass was exposed to light. However, if the rest of the plant was covered and only the tip exposed to light, the grass bent a few centimeters below the tip. How could light striking the tip of the grass cause bending a few centimeters from the tip
Answer:
The summary of the particular subject is provided in the segment below on clarification.
Explanation:
Noticed that saplings of the plant would still curve forward into light unless the tip of their ranges were available. The crop developed straight ahead as they cut the edge of such a grass crop, instead of just rotating forward towards the ground.The target stayed straightforward as they put an opaque caps over its end. However, when individuals positioned a transparent caps on its own edge, or perhaps an opaque mask over its core, it streamlined.This was found that perhaps the shoot's tip was essential to detect light. Acknowledged that although the answer to development, trying to bend the shooting, actually happens beneath the tip. A certain message was conveyed downwards from either the service charge to the take the shot's growing market.What are molecular clocks used for

Read the text: Trans fat is obtained industrially after certain vegetable oils, under certain conditions, are hydrogenated and transformed into solid fat. This type of fat has been used in the production of some food products, such as stuffed cookies, giving them, for example, a more crunchy consistency. However, it is admitted that the excessive consumption of trans fat contributes to obesity and the development of cardiovascular diseases. a) What group of lipids do oils and fats belong to? b) How can we differentiate oils from fats at room temperatures, around 20 ° C? c) Many seeds, such as soybeans, store relatively large amounts of oil. What is the importance of the presence of oil for the embryo of oil seeds? d) Birds and mammals store fats in adipose tissue, under the skin. What is the advantage of the fatty layer under the skin being especially developed in animals that live in cold climates, such as polar bears? e) Recent studies indicate that fat is associated with cardiovascular disease. Name another substance in the lipid group also commonly associated with these diseases.
Answer and Explanation:
a) What group of lipids do oils and fats belong to? Lipids and fats belong to the triglyceride group. Triglycerides are a mixture of glyceride esters and fatty acids. They are stored in specialized adipose cells, known as adipocytes. Adipocytes give a place to the adipose tissue in the organism.
b) How can we differentiate oils from fats at room temperatures, around 20 ° C? At room temperature, fats can be recognized for being solid, while oil is liquid.
c) Many seeds, such as soybeans, store relatively large amounts of oil. What is the importance of the presence of oil for the embryo of oil seeds? The plant´s embryo needs to nurture while it is developing. The oil in the seeds plays the role of nutritive storage, together with other nutritive substances. These are used by the plant until it is able to photosynthesize.
d) Birds and mammals store fats in adipose tissue, under the skin. What is the advantage of the fatty layer under the skin being especially developed in animals that live in cold climates, such as polar bears? The advantage of the fatty layer under the skin is to keep or maintain the animal´s temperature. It is very common to find a thick fatty layer under the skin of animals that live in very cold environments, such as polar bears or deep divers marine mammals.
e) Recent studies indicate that fat is associated with cardiovascular disease. Name another substance in the lipid group also commonly associated with these diseases. Cholesterol is a fatty substance needed for the good functioning of the organism. It is part of cellular layers and it plays a role in hormone synthesis and biliary salts. Although in excess they might be harmful as they tend to accumulate in the artery´s walls, blocking the passage of blood. This can lead to a heart attack.
