Sun's atmosphere consists photosphere, chromosphere, and corona. Hence option d is correct.
Sun is divided into two parts internal sun and atmosphere. In sun's atmosphere, it consists photosphere- the visible surface of the sun,
chromosphere- it is the transition state between the photosphere and corona.
The outermost hot shell of the atmosphere is the corona, these there layers males the sun's atmosphere.
These three layers make the sun's atmosphere apart from its internal structure, core, radiation zone, and convection zone these are three interior layers of the sun.
Therefore option d corona, chromosphere, and photosphere are correct.

Answer:
Lots of insects eat plants, some insects eat other insects, and some even drink blood. Many insects eat nectar from plants. And some insects will eat whatever scraps of food you leave lying around. A few insects, such as mayflies and some moths, never eat.

Answer:
sample response: Endotherms are able to maintain a constant body temperature. An endotherm may respond to a hot summer day by sweating or panting. The body temperature of an ectotherm, on the other hand, changes with its surroundings. In order to stay cool, an ectotherm must move somewhere cooler like the shade of a plant or rock or seek cool water to lay in
Explanation:
Answer:
which ones
Explanation:
Answer:
c. Oxidative phosphorylation yields a lot of ATP
Explanation:
Fermentation is an anaerobic process that takes place in the anaerobic bacteria to produce an energy molecule called ATP. The process of fermentation involves the breakdown of the glucose through glycolysis which produces 2 ATP molecules, NADH and Pyruvate molecules.
The process does not undergo further steps like the Citric acid cycle and the oxidative phosphorylation which forms the high number of ATP molecules.Since the organism which performs the fermentation does not undergo oxidative phosphorylation therefore the yield of ATP in the cell is very less.
Thus, Option-C is correct.
Answer: The basic tissue structure of the mucosa layer of the alimentary canal consists of:
--> mucous membrane
--> lamina propria
--> muscularis mucosa
Explanation:
The MUCOUS MEMBRANE forms the innermost layer of the alimentary canals which includes the stomach and the duodenum (small intestine) . It's major functions is protection, secretions and absorption. The type of mucous membrane found in the stomach and duodenum is the Columnar epithelial cells. Not numerous gastric glands are situated below the surface in the mucous membrane of the stomach. They consist of specialised cells that secrete gastric juice that aids in the digestion of food. While the duodenal mucosa consists of mucous producing goblet cells. These cells produce a viscous, alkaline mucus that protects against the acidic gastric juices and pepsin. The folding of these mucosal cells (microvilli) provides a large surface area to optimize nutrient absorption.
The LAMINA PROPRIA: This layer separates the mucous membrane and the muscularis mucosa. It is made up of connective tissues which supports the blood vessels that nourishes the inner epithelial layer. In both the stomach and duodenum, digested nutrients are absorbed into the capillaries.
MUSCULARIS MUCOSA: This is made up of thin layer of smooth involuntary muscles. The contraction and relaxation of these muscle layers occurs in waves, which push the contents of the tract onwards. This type of contraction is called peristalsis which occurs in the duodenum. While in the stomach, these muscles allows for the churning motion characteristic of gastric activities.
The mucosa layer in the alimentary canal comes into direct contact with food and consists of three layers: epithelium, lamina propria, and muscularis mucosae. The stomach mucosa secretes mucus, hydrochloric acid, and digestive enzymes, while the duodenum's mucosa contains glands that neutralize stomach acid, protecting the intestinal wall and enabling absorption.
The mucosa layer in the alimentary canal is the innermost layer that comes into direct contact with food. This layer consists of three sublayers: epithelium, lamina propria, and muscularis mucosae. The epithelium is made up of simple columnar cells responsible for secretion and absorption. The lamina propria is composed of loose connective tissue supporting the epithelium, and the muscularis mucosae is a thin layer of muscle that causes local movement of the mucosa.
The mucosa in the stomach has a special epithelium that secrets mucus, hydrochloric acid, and digestive enzymes, aiding in both protection and the breakdown of food. Its unique feature is the presence of gastric pits and parietal cells that secrete hydrochloric acid.
In contrast, the mucosa in the duodenum, part of the small intestine, contains Brunner's glands which produce an alkaline secretion rich in bicarbonate and mucus. The purpose of this is to neutralize stomach acid and protect the intestinal wall, enabling absorption to take place.

c) Individual III and I12 are considering having another child. What is the probability that
this child will have Marfan syndrome? Explain using a Punnett square.
Answer:
The correct answers are :
a) syndrome Could be autosomal recessive or dominant
b) If it is autosomal recessive - no,
and if it is autosomal dominant - yes, (II-4) - Aa
c) probability of the another child :
Autosomal recessive: Aa x aa 50%
Autosomal dominant: aa x Aa 50%
Explanation:
a) Marfan syndrome could be inherited by the autosomal recessive or dominant pattern on the basis of following characters according the pedigree gives:
- transmitted by anyone regardless of sex male or female
- characters should not skip generations
- A cross between affected person and an normal person should produce approximately half of the affected offspring.
b) Assuming that autosomal dominant than there is two possibilities :
1) in case of I 2 genotype is heterozygous which means it is Aa which will produce Aa Aa aa and aa with crossing with aa as per pedigree however it is incorrect according the offspring given in II.
2) If I 2 is AA- then offspring will be Aa, Aa, Aa and Aa. which is correct according the pedigree.
thus, the answer is - Aa
c) the punnet square as per question is :
II2 - Aa × II1 - aa
A a
a Aa aa
a Aa aa
similar with autosomal recessive
thus, the correct answer is 2 out of 4 that is 50%
