Answer:
The blood pumped by the heart is transported to different parts of the body to deliver oxygen.
Explanation:
Homeostasis is a process whereby living cells maintain a stable internal environment despite changes in their external environment. One way cells perform homeostasis is by ensuring oxygen gas, which is required for cellular respiration, reaches all the cells. However, the circulatory and respiratory systems work hand in hand to fulfill this.
The respiratory system brings in oxygen present in air, which is then carried by a pigment in the blood called haemoglobin, to every part of the body. Hence, respiratory system brings in the oxygen gas while circulatory system ensures the oxygen gas is everywhere in the body.
Answer:
The blood pumped by the heart is transported to different parts of the body to deliver oxygen.

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:
Periods of light-time Temperature Substrate/Soil typeExplanation:
Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.
These variables must be the same for all the subjects or groups (control and experimental). In the case of plants, controlled variables are probably those needed by the plants to correct development.
All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.

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.

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!

3.How have scientists' ideas of human evolution changed over time
Please Hurry
Answer:
They once thought that humans came from monkeys and apes but now they think they come from a ancient ancestor not from the monkey or ape family.
Explanation:
A human general manner of life, including what it consumes, how it grows, and where it may dwell, might change throughout time as a result of genetic change.
What is human evolution?New genetic variations in early ancestor populations favored new capabilities for environmental adaptation, which then in turn altered the human way of life and facilitated human development.
It is generally accepted that the development of modern humans from our hominid ancestors involves four main stages in evolution, developing terrestriality, bipedalism, a huge brain (encephalization), and civilization.
They more than likely came from Africa within the last 200,000 years, an ancient form of human called Homo erectus
Therefore, Homo erectus, meaning means "upright man" in Latin, is most likely the most recent common ancestor of today's humans,

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.

Answer:

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.

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
