The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called... *
Answer:
Phylogenetic tree
Explanation:
A phylogenetic tree is a tree that is responsible for showing the different relationships with respect to evolution between species that are considered to have a common offspring. The species of interest are shown at the tips of the branches of the tree in question. The branches are connecting with each other, representing the evolutionary history of the species, being the way in which we think that they evolved starting from a common ancestor through various divergence events (when two branches separate).

Explain the various phase of menstrual cycle with reference to changes in ovary and uterus and hormonal cycle.
Answer:
In the follicular phase, the follicles grow inside the ovary. The ovulatory phase is the time of greatest fertility for women. In it, estrogen levels peak just before the egg is released. In the luteal phase, after ovulation the follicular structure that remains in the ovary reorganizes and becomes a gland known as the corpus luteum. The self-determined life of the corpus luteum causes it to degenerate after 14 days and end a menstrual cycle. At the end of the luteal phase, progesterone and estrogen levels drop and menstruation occurs.
Explanation:
The follicular phase is where follicles develop (fluid-filled cavities in the ovary that contain an undeveloped egg) that will eventually house the egg. For the development of follicles, the body sends a signal to the brain to start the production of follicle stimulating hormone (FSH), the follicles begin to develop and produce estrogen. In the ovulatory phase, the level of estrogen in the body continues to rise, causing a rapid rise in LH. This increase causes the secretion of proteolytic enzymes that will degrade the follicular tissue allowing the maturation process of the ovum and its release to finish, a fact known as "ovulation". Ovulation usually occurs between 24 and 36 hours after the LH surge, so luteinizing hormone is a good factor for measuring the period of maximum fertility and knowing the fertile days of the woman. In the luteal phase, the corpus luteum develops that will last until a possible pregnancy or menstruation occurs, starting the next cycle. The egg, after being released, travels through the fallopian tube to the womb. It can survive up to 24 hours and sperm up to 5 days inside the uterus, therefore the days before ovulation and the day of ovulation itself, which can be calculated with the ovulation calendar, are those of maximum fertility and higher chances of pregnancy. After ovulation, the follicle begins to contract but continues to produce progesterone and begins to produce estrogen in order to continue preparing the uterus to receive the embryo.

The principle of natural selection states that the best adapted organisms are most likely to survive and reproduce. Was this demonstrated in your experiment? Explain.
Answer:
Yes
Explanation:
Natural selection was first postulated by Charles Darwin. It is the idea that organisms that are best adapted to their environment are able to survive and reproduce thereby transmitting their favorable characteristics to their offspring.
In our experiment, the insects that were able to survive were allowed to reproduce thereby transmitting their favorable characteristics to their offspring. This is a demonstration of natural selection.

What is Transpiration?Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.
Transpiration is essentially evaporation of water from plant leaves. Transpiration is important because water is needed for photosynthesis and because water cools a plant off.
Thus, option "C" is the correct answer.

explain the global water crisis in your own words
Explanation:
Water is the basic necessity of every human being. But, water scarcity is a major issue that is rising very rapidly in modern-day India. The problem has become so severe that in many states the groundwater has almost dried up and people have to depend on water supply from other sources. In addition, water is one of the most misused commodities that we still waste. It is the central point of our lives but not the central point of our focus.
In the past, people understand the value of water and plan their lives around it. Moreover, many civilizations bloom and lost on account of water. But, today we have knowledge but we still fail to understand the value of water.
Reason for Water Scarcity in India
Water scarcity is the cause of mismanagement and excess population growth of the water resources. Also, it is a man-made issue that continues to rise. Besides, some of the reasons for water scarcity are:
Wasteful use of water for Agriculture- India is one of the major food growers in the world. That produces tons of quantity of food to feed its population and export the surplus that is left.
In addition, producing this much food requires a lot of water too. The traditional method of irrigation wastes a lot of water due to evaporation, water conveyance, drainage, percolation, and the overuse of groundwater. Besides, most of the areas in India use traditional irrigation techniques that stress the availability of water.
But, the solution to this problem lies in the extensive irrigation techniques such as micro-irrigation in which we provide water to plants and crops using a sprinkler or drip irrigation.
Reduction in water recharge systems- Due to rapid construction that uses concrete and marbles do not let the rainwater to get absorbed in the soil. But, if we install some mechanism in our houses that can hold the rainwater then we can recharge the groundwater.
Lack of water management and distribution- There is a need for an efficient system that can manage and distribute the water in urban areas. Also, the government needs to enhance its technology and investment in water treatment. Besides, we should ensure optimization at the planning level.
Solutions to Overcome this Problem
Water-free urinal- Urinal waste around 6 liters of water per flush that add up to 25 thousand liters per year. If a male member of the house stops using the flush then they can save lots of water.
Close the running tap- During dishwashing and hand washing people often let the tap running. These running taps waste thousands of liters of water per year. Besides, closing the tap will reduce this problem.
Replace dripping taps- In India it is commonly seen that most of the houses have one or two taps that drop water even when they are close. This running tap wastes up to 30,000 liters of water that nobody bothers to change. So, we should replace these taps immediately.
To conclude, water scarcity has become a more dangerous problem day by day. Also, due to our leniency that we haven’t taken the problem water scarcity seriously. But, now the authorities and people are working to resolve this problem so that our future generations do not have to buy this necessity.

What role does the Krebs cycle play in the cells
Horses and donkeys can breed and produce sterile offspring known as mules. Horses and donkeys remain separate species because of this hybrid sterility, which is a(n) Group of answer choices post-zygotic barrier to reproduction. sympatric barrier to reproduction. pre-zygotic barrier to reproduction. allopatric barrier to reproduction. good thing.
Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.
The biotic factors that affect an organism include other species in that organism’s community.
