The cubs are a significant barrier to reproduction when a new male coalition first takes control of a pride. Mothers of surviving cubs won't mate again until their young are at least 18 months old, but if their cubs are lost, they will mate right away.
Following that, males leave on their own or are driven out by other men who take control of their pride. It is common for a new male to kill all the cubs when he joins the pride in order to pass his genes on to all future cubs. The major function of males in the pride is defending the pride's territory.Female lionesses will devour the cubs of other pride, but not the cubs of their own pride. The "egalitarianism" of female lions stands in stark contrast to the autocratic behavior of wolves, wild dogs, and several other species, where dominant females prevent subordinates from reproducing.When a female lion gives birth, she leaves the pride and doesn't come back until the cubs are several weeks old. After that, the adult females band together to take care of and protect the young.Learn more about pride here:

Q.N (1) Give reasons
(1) Nebula is also known as staller nursery.
(2) We cannot see or observe the blackhole.
A stellar nursery was a sort of nebula where young stars were created by the pressure and heat of colliding energy. Blackhole.
Why do we can not see blackhole?
A black hole is an area in space where gravity is so intense that not even light can escape. The gravity is very strong since the stuff is compacted into such a small space. This might occur when a star ages. Humans cannot see black holes because light cannot escape from them.
This suggests that from a distance, the gravitational field of a black hole like this one is identical to the gravitational field of any other spherical object with the same mass.

Brown-eyed alma has a blue-eyed mother and a brown-eyed father. In this case, her brown eyes were determined by a _____ allele.
In this instance, a dominant allele was responsible for her brown eyes.
Dominant alleles: what are they?A dominant allele is a gene variant that, even in the presence of other alleles, will cause a certain phenotype.Usually, a dominant allele codes for a protein that functions. One copy of the allele generates enough enzyme for a cell to have an abundance of a certain product, which is why the allele is dominant.What makes a gene a dominant allele?Because it hides the recessive trait and manifests in the phenotype of a heterozygous creature, a dominant allele is referred to as dominant. It takes just one allele to express the characteristic.learn more about dominant allele here

The complete diagram is shown below in the image representing the stages of meiosis.
Mitosis as well as meiosis are both types of division of the nucleus in the eukaryotic cells. The complete diagram shows that Meiosis comprises of two nuclear divisions which lead to the formation of four nuclei which are generally divided resulting in the creation of four new haploid cells.
The nuclei that are formed by the process of meiosis are not genetically identical unlike mitosis. During Meiosis I, the synapsis of homologous chromosomes occurs, chiasmata formation and crossing over takes place. The sister chromatids also align along the Metaphase plate in tetrads.

How Cytoplasmic soup is formed?
Answer:
It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm.
Explanation:
Hope it helps
Mark as brainliest:D
Answer:
The cytoplasm (also known as cytosol) is the protoplasm of a cell outside the cell nucleus. It is the jelly-like material plus the organelles outside the nucleus, and inside the cell membrane.
Many important functions of a cell take place in organelles, which are like bits of machinery for doing many jobs. The cytoplasm is highly structured: it is not some kind of soup, even though it is made out of 75–80% water.
The cytosol contains a complex mixture of cytoskeleton filaments, including the endoplasmic reticulum and the Golgi apparatus. It includes dissolved molecules, and water that fills much of the cell. Due to this network of fibres, membranes and the many dissolved macromolecules such as proteins, the cytosol does not act like a simple liquid. The main function of the cytoplasm is to hold the organelles in place

explain the role of diaphragm in the process of breathing
Answer:
The diaphragm muscle contacts and relaxes to force the intake and expulsion of air from the lungs.
Explanation:
The diaphragm is a large, dome-shaped skeletal muscle. It is very thin, and is located at the base of the chest just above the abdomen. It plays a very important role during respiration or breathing by forcing the intake and expulsion of air from the lungs.
During inhalation, this muscle contracts, and flattens- in the process, a vacuum is created, effectively pulling air into the space. In exhalation the muscle relaxes, and is no longer flattened, this reduces the volume of the region, forcing air out of the lungs. These contractions occur rhythmically and continuously.
