HUMAN BODY SYSTEMS QUICK GUIDE
Circulatory : Transport gasses(oxygen,CO2) and nutrients throughout body;
Digestive: Breakdown of nutrients (food);
Nervous: Process & respond to stimuli;
Respiratory: Gas exchange;
Muscular: Movement;
Excretory: Eliminates waste to maintain homeostasis;
Immune: Defense against disease
Answers
Answer: the human body is made up of multiple interacting systems, within the systems there are 3 that really work together. for starters, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells. Working along these cells is the digestive system, the human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body which then provides nutrients that give the body energy.

a homozyguos curved-horned stallion is crossed with a spiral-horned mare.
What is the mare’s genotype (with respect to her horn)?
What proportion of the offspring will have a heterozygous genotype? (Percentage)
What proportion of the offspring will have a homozygous genotype? (Percentage )
What proportion of the offspring will have a curved horn phenotype?
What proportion of the offspring will have a spiral horn phenotype?
Answers
Let us assume that the genotype for curved horns is C (dominant) and spiral horns is c (recessive).
Finding the mare's genotype,
Parents: CC x cc
F1 Generation (Mare): Cc, Cc, Cc, Cc (After meiosis.)
It can be seen that all the 4 mares in the F1 generation are hybrid (heterozygous) with curved horns, since the recessive gene doesn't express itself because of the heterozygous genotypes.
Since all four offspring have a heterozygous genotype, proportion of the offspring having a heterozygous genotype = 4/4 = 100%.
Since none of the offspring have a homozygous genotype, proportion = 0/4 = 0%.
Proportion of the offspring that will have a curved horn phenotype = 4/4 = 100%
Proportion of the offspring that will have a spiral horn phenotype = 0/4 = 0%.

the flower of another plant of the same species. Write a journal
entry in complete sentences describing your journey. Correctly
include each of these terms in your entry: pollinator,
pollen, pistil, stamen, anther, stigma, ovary, and eggs
Answers
Answer:Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
Explanation: i hope this can give you a little push!
Answer:
As a grain of pollen on a flower, I am responsible for cross-pollinating the flower of another plant of the same species. I began my journey on the stamen of one flower, where I picked up the pollen from another. I was carried to the pistil of the next flower and deposited the pollen on the stigma. I then traveled down the style to the ovary, where I fertilized the eggs, commencing the production of the next generation of this flower.
A mother and father have two daughters. The daughters have some similar and some different physical features. Which statement best explains why the daughters’ physical appearance includes both similar and different features?
A: One daughter received fewer genes than the other.
B: Each daughter received a different number of genes from each parent.
C: The daughters received a random set of genes from both of their parents.
D: One daughter received all her genes from her father, and the other daughter received all her genes from her mother
Answers
C: The daughters received a random set of genes from both of their parents.
The physical appearance of an individual is determined by their genes, which are inherited from their parents. Each parent contributes half of their genes to their offspring, and the combination of genes from both parents determines the physical characteristics of the offspring.
When the two daughters inherit genes from both their parents, they receive a random set of genes from each parent, which can result in both similar and different physical features. Therefore, statement C is the best explanation for why the daughters' physical appearance includes both similar and different features.

Answers
1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.
2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.
3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.
4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.
5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.
6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.
7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.
8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.
Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

How do you think the sequence of amino acids in an enzyme relates to its ability to bind to a specific target molecule?
Answers
Answer:
The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). ... Thanks to these amino acids, an enzyme's active site is uniquely suited to bind to a particular target—the enzyme's substrate or substrates—and help them undergo a chemical reaction.
Explanation:
Enzymes are biocatalyst that accelerates the rate of chemical reaction without itself being consumed. Enzymes are mostly proteins.
The binding of enzyme with substrate is highly specific. A given enzyme usually binds to only one kind of substrate. The substrate binds to the enzyme at the active site.
Active site is the region of an enzyme where the substrate binds. The active site consist of sequence of amino acid residues which is uniquely suited to bind to a specific substrate.

Homologous structures are assumed to: • Have different functions •Have the same evolutionary origin •Have the same function •Have different evolutionary origins
Answers
Answer:
Have the same evolutionary origin
Explanation:
Predicting the evolutionary relationship between organisms require certain structures, which are used as evidence. These structures can either be homologous or analogous.
Homologous structures are those structures of organisms that have a similar embryonic or evolutionary origin i.e. share common ancestors. For example, the wings of a bat and the arm of humans are homologous structures because they are found to be from the same evolutionary origin. Although, they appear different and perform different functions but using genetical means (DNA), they have been found to share a common ancestor.
On the other hand, analogous structures are structures that perform similar functions and are physically similar but they evolved from different evolutionary origins.

The following map shows the average monthly precipitation in the western United States. The areas in dark blue have very high amounts of precipitation and the areas in orange have very low amounts of precipitation. Image courtesy of USGS Why is there so much more precipitation near the coast than in other areas?
A. It is close to the ocean, and moisture from the air above the ocean moves eastward to the coast where the precipitation often occurs.
B. The water near the northwest does not produce enough moisture for winds to carry it to the rest of the area.
C. The water near the coast does not get heated enough to cause precipitation in the rest of the area.
D. The land and the water have different temperatures, so warm fronts and cold fronts constantly exist above the coast.
Answers
Answer:
Its B
Explanation:
There is so much more precipitation near the coast than in other areas as the water near the northwest does not produce enough moisture for winds to carry it to the rest of the area. Therefore, option (B) is correct.
Why is precipitation is more in coastal areas?Due to the high humidity of the clouds near the coast, coasts receive more precipitation than interior continents. They have already shed water in the form of rain when they reach the interior of the continents, so there is not much humidity left to cause rain.
Southeast Asia's monsoon region and the equatorial zone receive the most precipitation. Center scopes get moderate measures of precipitation, yet little falls in the desert locales of the subtropics and around the shafts.
The Northeast monsoons, which draw moisture from the Bay of Bengal, are responsible for the majority of the rain that falls on the Coromandel coast during the winter.
