Answer:4
Explanation:
For every bond created, four water molecules must be removed. Bonds break and join when molecules are formed.
What are chemical bonds?Different types of chemical bonds are present between different types of compounds, these bonds store energy and when the chemical reaction happens the reactance reacts they broke the bonds from the energy and create new compounds.
It takes a lot of heat to raise the temperature of liquid water, and an exceptional amount of heat to evaporate a given volume of water because hydrogen bonds need to be broken for the molecules to escape as gases.
Hydrogen bonds release water when they join or break. These bonds are formed in water and other compounds like DNA bases.
Therefore, four water molecules must be eliminated for every new link that is formed. When molecules are produced, bonds are broken and joined.

During meiosis, genetic recombination results because –
a: Genes from different species can freely mix together.
b: Chromosomes assort independently and crossing-over occurs.
c: Gene mutation occurs more frequently than at other times.
d: Cells divide only once, resulting in genetically identical cells.
Answer:
b: Chromosomes assort independently and crossing-over occurs.
•Crossing-over results in genetic recombination by producing a new mixture of genetic material. Each homologous pair consists of four chromatids, because each chromosome in the pair had replicated before meiosis began. Homologous pairs (tetrads) are still paired together and arrange in the middle of the cell.

When you workout, your cells need energy for muscle contraction. In order to get this, your body will carry out a process called cellular respiration. During this process, glucose (taken from food) is broken down in the presence of oxygen to make usable form of energy cells, called ATP. This process converts chemical energy from the bonds of food molecules into energy that is stored (potential energy) in ATP molecules. The process also releases heat (thermal energy), which is why you feel warm. Your body carries out this amazing process to fuel your workouts!

Answer:
Explanation:I believe there are five main reasons for the declines experienced in several Midwestern states.
1 – Hemorrhagic Disease
We had a record hemorrhagic disease (HD) outbreak in 2007 and another in 2012. The Midwest lost tens of thousands of deer to HD and many states haven’t fully recovered from it.
2 – Severe Winter Weather
We experienced severe winter weather during the past few years. Severe winters in the Upper Midwest can increase adult mortality, reduce fawn survival, and impact antler growth the following year as bucks have to recover the additional weight lost during the severe winter. This leaves less nutrition for antler growth.
3 – Intentional Herd Reduction
Several states were intentionally reducing their deer herds over the past decade. Many states were aggressively harvesting antlerless deer, and when you reduce the herd the buck harvest declines. In the Midwest today, only one state wildlife agency (Indiana) says it is trying to reduce the deer herd, the others are either trying to stabilize or grow their herds.
4 – Falling Fawn Recruitment
Eight states in the Midwest measure fawn recruitment rates today. In my opinion, every state should be monitoring this important statistic. Back in 2005 only five of the eight states measured fawn survival, and it has dropped in all five from 2005 to 2014. You can blame it on predators, nutrition, climate change, or whatever you’d like, but the reality is far fewer fawns are surviving today than they did a decade ago. Approximately every other fawn born is a buck fawn, so fewer fawns means fewer bucks are recruited into the herd.
5 – Habitat Loss
The last reason is arguably the most important in this list, and it is habitat loss. From 2007 to 2014 the U.S. enrolled 9.1 million fewer acres into the USDA’s Conservation Reserve Program (CRP). The CRP is the most successful federal wildlife habitat program, and it pays landowners a fee to convert highly erodible cropland and environmentally sensitive acreage to wildlife habitat. It can include grasses, trees, windbreaks, shelterbelts, buffer strips and more. In most cases, CRP acres provide exceptional wildlife habitat, and this is especially true in the intensively row-cropped Midwest where cover was already the limiting habitat component.

Answer:
Reorder the terms:
8 + 6p + -4p = 3(p + 4)
Combine like terms: 6p + -4p = 2p
8 + 2p = 3(p + 4)
Reorder the terms:
8 + 2p = 3(4 + p)
8 + 2p = (4 * 3 + p * 3)
8 + 2p = (12 + 3p)
Solving
8 + 2p = 12 + 3p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-3p' to each side of the equation.
8 + 2p + -3p = 12 + 3p + -3p
Combine like terms: 2p + -3p = -1p
8 + -1p = 12 + 3p + -3p
Combine like terms: 3p + -3p = 0
8 + -1p = 12 + 0
8 + -1p = 12
Add '-8' to each side of the equation.
8 + -8 + -1p = 12 + -8
Combine like terms: 8 + -8 = 0
0 + -1p = 12 + -8
-1p = 12 + -8

Answer:
Punctuated equilibrium refers to B. Species that evolved very rapidly during relatively brief time spans
Explanation:
The theory of evolution states that organisms heritable characteristics change over time to form new lineages or species. Punctuated equilibrium is an evolutionary theory that explains the sudden appearance of novel species on the fossil record. In this theory, the species likely evolved quickly to survive in a significantly altered environment.

Describe how a species is commonly defined. Explain why the common definition for species may be problematic for some organisms, such as bacteria.
Answer:
Species are commonly defined as problematic organisms like bacteria because they do not reproduce sexually. They are defined based on genetic similarity.
hope this helps!!:)
Explanation:
Species are frequently referred to be undesirable organisms because they do not undergo sexual reproduction. On the basis of genetic similarity, they are classified.
What are species ?A group of creatures that can naturally reproduce with one another and generate viable progeny is sometimes referred to as a species. However, classifying a species can be challenging and even contentious.
A lion and a tiger are two examples of organisms that can reproduce but do not generate fruitful offspring since they are not of the same species. They are not of the same species as a result. A group of organisms that can reproduce and create sterile offspring is referred to be a species.
A species is a group of living things that are all essentially similar to one another and may, in theory, reproduce with one another. Although it seems simple enough, defining the term "species" can be incredibly challenging.
Thus, Species are frequently referred to be undesirable organisms because they do not undergo sexual reproduction.

Answer:
Cell membranes had formed
Explanation:
I hope it helped
The Miller and Urey experiment showed for the first time that the organic molecules necessary for life could be formed from inorganic components.
In 1953, scientists Stanley Miller and Harold Urey experimented to verify that organic molecules could form spontaneously under environmental conditions similar to those of the Earth in its early days.
To do this, they built a closed system in which they included a container with hot water and a mixture of gases that supposedly abounded in the Earth's atmosphere at the beginning. In addition, they devised the way to simulate lightning bolts that provided energy for chemical reactions in the atmosphere.
After running their experiment for a week, they resulted in the formation of various types of amino acids, sugars, lipids, and other organic molecules. This experiment allowed them to show that at least some of the structural units of these molecules could form spontaneously from simple compounds.
