Answer:
Information:Symbiotic relationships are important because they are a major driving force of evolution. This networking and cooperation among species allows them to survive better than they would as individuals.
Genetic Technology: Write a scientific explanation to explain the multiple technologies that humans
can use to affect traits in organisms. Use evidence to describe the processes and give examples. Give
at least two examples
Answer:
Examples of genetic technologies:
- High-yield maize varieties by conventional breeding
- Production of hormones by transgenic or genetically engineered microbes
Explanation:
Genetic improvement refers to the use of technologies in order to develop and select individuals with desired phenotypic traits. These genetic technologies can be divided into 1-conventional genetic improvement approaches based on the development of individuals (e.g., new plant varieties) by crossing together individuals with desired characteristics and subsequent rounds of artificial selection, and 2-modern genetic technologies where genes are directly manipulated in the laboratory through genetic engineering technologies such as, for example, the use of transgenic methods (e.g., DNA microinjection, retrovirus-mediated gene transfer, etc), or the CRISPR-Cas9 genome editing system (which can be used to edit target genes of interest), etc.

PLEASE HELP!!
*50 points to whoever can answer that question and draw a flowchart, thank you*
Answer: The ETC is the last part of cellular respiration. In the first steps of cellular respiration (glycolysis and Krebs cylce), electrons are freed from glucose derived molecules. In the ETC the electrons are passed on through a series of proteins in the inner membrane of the mitochondria. The electrons in a sense 'flow' to lower energy levels (see image), they lose energy in the process.
Energy produced by H+ travelling via ATP synthase and down a concentration gradient is used by chemiosmosis. ADP is phosphorylated with this energy to create ATP.
What is Chemiosmosis?Chemiosmosis is the passage of ions along their electrochemical gradient through a semipermeable transmembrane domain structure. Adenosine triphosphate is created when hydrogen ions pass a membrane during photosynthesis or cellular respiration. This is a significant example.
The process of ions (often H+ ions, commonly referred to as protons) diffusing across a membrane that is selectively permeable is known as chemiosmosis. Chemiosmosis produces a concentration gradient of a diffusing ion from across membrane, similar to osmosis. Potential energy that can perform work is present in concentration gradients.
Thus, energy produced by H+ travelling via ATP synthase and down a concentration gradient is used by chemiosmosis. ADP is phosphorylated with this energy to create ATP.

9. What processes make these different types of rocks?
10. What properties are used to identify some of these rocks?
11.What are the most important minerals on Earth?
12.What are the importance of minerals on the earth?
9. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
10.Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage.
11.The feldspar-group, a very complex mixture of oxygen, silicon, aluminum and trace elements like sodium, potassium, calcium and more exotic elements like barium, are by far the most common minerals, making up almost 58% of all to a geologist accessible rocks, especially magmatic and metamorphic ones.
12.minerals are really very important in our life as they are used in our daily purposes and we use for example iron daily we use iron almirahs etc ,......
we use aluminium, diamond etc . in our daily life we use aluminium foils that are used to pack food items etc ,. there are many examples such as these ....
Minerals are play important role in our life. Everything we use from a tiny ship to tower are building is made from a mineral. We use minerals in our daily life for example tooth paste its cover and brush everything is made from minerals. All living things also need minerals
Which of the following is a definition of the process of natural selection?
a) In each generation, some individuals may, just by chance, have more offspring than other individuals and their traits will become more common in that population.
b) More advantageous traits in a particular environment allow individuals with those traits to have more offspring; as a result their heritable traits become more common in succeeding generations of the population.
c) Mutations occur at random in a population causing populations to change over time as those mutations are inherited from one generation to the next.
Answer:
C
Explanation:
Mutations occur oftenly in organisms because it is seen as natural. Not all generations will give offsprings with perfect traits, They tend to have either 50/50 inherited traits from each parent of 100% off a parent if it was asexual reproduction.

What type of reproduction involves forming offspring from two
parents?
a Asexual
b Sexual
C Mitosis
int?
d Replication
Answer:
Sexual
Explanation:
Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
Hope it helps
Answer: Sexual, I believe.
Explanation:
If it were Asexual, it'd only involve one parent. Mitosis has daughter cells have the same number of chromosomes as parent cells (heavy emphasis on cells as in plural cells.) And replication is just copying a cell.

What is the independent variable of great white sharks travelling distance?
Answer:
Each year, great white sharks migrate over long distances from their feeding grounds off the central California coast to other feeding grounds far away in the Pacific Ocean. ... That's one reason they migrate from one feeding ground to another, to take advantage of the seasonal bounty.
It's though that a shark can travel up to 50 miles in one day. While we cannot know this for certain as sharks have never been tracked this way, 50 miles is a good estimate

Which of these factors is associated with sustainable farming?
O A. Overly irrigated soil
O B. No-till farming
O C. Intensive farming
O D. Monoculture
Answer:
No-till farming
B. No-till farming is associated with sustainable farming.
What is No-till farming?No-till farming is a farming method where the soil is not disturbed or tilled, but rather the crop residues are left on the surface of the soil. This helps to reduce soil erosion and improve soil health, and also helps to sequester carbon in the soil, which can help to mitigate climate change.
Other sustainable farming practices include crop rotation, agroforestry, and integrated pest management, all of which prioritize the long-term health of the soil, the ecosystem, and the community over short-term profits.
In contrast, intensive farming involves high-input and high-output agricultural practices that prioritize maximizing production and yield, often at the expense of environmental and social sustainability.
This type of farming may use excessive amounts of synthetic fertilizers and pesticides, which can harm the environment and potentially pose health risks to humans and animals.
Monoculture, or the practice of growing a single crop in a large area of land, is another unsustainable farming practice. This practice can lead to soil depletion, increased pest and disease pressure, and reduced biodiversity, which can ultimately lead to decreased productivity and long-term negative impacts on the environment.

Factors that influence the size of ocean waves include how
Answer:wind strength
Wind velocity, wind timeframe means how long the wind blows, and fetch, which is the distance over water that the wind blows in a single direction, all influence wave height.
What are ocean waves?The splendor of the sea is also displayed by sea waves. The waves propagate the restlessness of the vast ocean. It also symbolizes faith, presume, and joy even in the most difficult of circumstances.
Wind waves in the ocean, also known as ocean surface waves, are primarily gravity waves.
Wind ripples have some randomness to them: subsequent waves vary in height, length of time, and shape with restricted consistency.
The wind is the most frequent cause of waves. Wind-driven waves, also known as surface waves, are caused by the friction of wind and surface water.
A wave crest is formed when wind picks up across the surface of the ocean or a lake.
Thus, Wind velocity, wind timeframe means how long the wind blows, and fetch are the factors that influence the waves of ocean.

EXPLANATION:❈ Leptotene —
➥ The chromatin network opens out and threads become clear.
➥ The chromosomes are thin, slender and long.
➥ Chromosome number is diploid.
❈ Zygotene —
➥ Corresponding chromosomes become intimately associated.
➥ The process of pairing is known as synapse. It is so exact that pairing is not merely between corresponding chromosomes but between corresponding individual units.
➥ The chromosomes become shorter and thicker.
❈ Pachytene or Pachynema —
➥ The synaptic chromosomes become very intimately associated.
➥ The pair of chromosomes becomes short and thick.
➥ Crossing over occurs at this stage. Chiasmata are clearly seen.

The difference between pinocytosis and receptor-mediated endocytosis is that _____. Question 14 options: pinocytosis can concentrate substances from the extracellular fluid, but receptor-mediated endocytosis cannot. pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity. pinocytosis brings only water molecules into the cell, but receptor-mediated endocytosis brings in other molecules as well. pinocytosis increases the surface area of the plasma membrane, whereas receptor-mediated endocytosis decreases the plasma membrane surface area.
Answer:
The difference between pinocytosis and receptor-mediated endocytosis is that pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity.
Explanation:
Pinocytosis and receptor-mediated endocytosis are two types of endocytosis.
The first one consists of plasmatic membrane invaginations that capture extracellular fluid with different nutrients and sends it to the inside of the cell in vesicles. The second one, receptor-mediated endocytosis, consists of receptors on the outside of the plasmatic membrane and clathrin proteins on the interior side of the membrane. When the receptors are in contact with its specific molecule, a vesicle surrounded by clathrin proteins, is formed transporting specific molecules to the cell's interior.
