Explain how the cell theory developed.

Answers

Answer 1

Explanation:

The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory.

natural selection will favor traits that

Answers

Natural selection doesn't favor traits that are somehow inherently superior. Instead, it favors traits that are beneficial (that is, help an organism survive and reproduce more effectively than its peers) in a specific environment. Traits that are helpful in one environment might actually be harmful in another.

what is living thing that work together to coexist?

Answers

Answer:

When a group of individual organisms live together in one place we call it a population. A population is defined as a group of organisms from the same species that live together in the same area.

Explanation:

Coexistence: living harmoniously with wildlife in a human-dominated world is a primer on IFAW’s mentality that coexistence is better than conflict. People’s relationship with native wildlife is often that of conflict. Animals such as coyotes, wolves, bears, and beavers are considered “nuisances” and are treated as something to be controlled. The result is millions of animals killed in barbaric ways every year by governments, all to “reduce conflict.” This report highlights examples of people finding innovative, yet simple ways to coexist with wildlife so that we can live side by side with these species. IFAW understands that not only are native wildlife species important to protect, but they are also essential to the ecosystem and therefore our own well-being. We work every day to make the planet a better place for both people and animals.

List three (3) tests that can be done on a soil sample and their significance.​

Answers

Moisture determination - one of the most important and most widely used measurements in the processing and testing of foods. Since the amount of dry matter in a food is inversely related to the amount of moisture it contains, moisture content is of direct economic importance to the processor and the consumer.

Atterberg limits tests - establish the moisture contents at which fine-grained clay and silt soils transition between solid, semi-solid, plastic, and liquid states. ... Casagrande refined and standardized the tests, and his methods still determine the liquid limit, plastic limit, and shrinkage limit of soils.

Soil Compaction Testing - a crucial step in the construction process. Ground that has not been properly compacted can be detrimental to the structural integrity of buildings, retaining structures, roads and pavements, just to name a few. Essentially, proper soil integrity could make or break your structure

By what process do glucose and fructose bond together to form sucrose (D)? What is the by-product of this reaction?

Answers

Answer: dehydration synthesis; water

Explanation:

When a monomer of glucose and a monomer of fructose combine to create a glycosidic bond during a dehydration reaction, sucrose is the result. One water molecule is lost throughout the process.

What is  process do glucose and fructose bond together?

The disaccharide sucrose is created through the condensation process between glucose and fructose.

One type of disaccharide is sucrose, also referred to as table sugar. Two monosaccharides are joined to create a disaccharide, which is a type of carbohydrate.

By joining the monosaccharide sugars glucose and fructose, sucrose is a disaccharide, or two-part molecule.

When honeybees ingest plant nectar, they break down the sucrose molecules using an enzyme called an inverstase to produce honey, which is mostly a mixture of sucrose, glucose, and fructose.

Therefore, glycosidic linkage glucose and fructose bond together.

Question 12 (6 points)
Answer the following relating to PHOTOSYNTHESIS and CELLULAR RESPIRATION
for 2 points each:
1. Identify WHERE each process occurs in cells.
2. Identify what EACH process needs and makes.
3. Explain how photosynthesis AND cellular respiration are important to the carbon
cycle.

Answers

1. Photosynthesis occurs in the Chloroplast, which contain a chlorophyll whereas Cellular Respiration takes place in the double-membrane organelle called the mitochondrion.

2. PHOTOSYNTHESIS:

6CO2 + 6H2O → C6H12O6 + 6O2.

The reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll into a sugar molecule and six oxygen molecules, the products.

CELLULAR RESPIRATION :

C6H12O6 + 6O2 → 6CO2 + 6H2O.

The equation for cellular respiration is the direct opposite of photosynthesis.

3. Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Using the list of events in the article, complete the diagram to show a cause, its effects, and then the response. Please help me 
:(

Answers

Answer and Explanation:

Cause: The plague swept across Europe.

Effects:

1. Production slowed down

2. The price of grain dropped.

3. The population of cities fell

Response: Italians began making wine, oil, and cheese.

(This is correct assuming that the plague occurred first when stated in the article)

So, why is it like this?

We know that a plague is a infectious and super contagious disease that can be transmitted by infected fleas, and is known for killing many people.

So, it makes sense that because this plague happened, we would see a price of grain drop, since the amount of workers were shortened from the plague, and there are less people to buy the grain for the factories and businesses to gain the money from the people's shopping of grains.

That has the production slowed down, so there is less food and grain, and the population would decrease as people were dying from the plague.

This results in the Italians making wine, oil, and cheese to combat the plague.

I'm sorry if this is wrong, and hopefully the article tells you in order the events that occurred. This is my best guess, and what makes sense to me.

Why DMD mostly affects boys?

Answers

DMD affects boys because the dystrophin gene is on the X chromosome. Chromosomes are the parts of your cells that contain your genes. Boys only have one X chromosome. Girls have two X chromosomes, one from each parent.

Answers

Answer:

1.5m/s

Explanation:

Using the formula;

Speed (m/s) = distance (metres) ÷ time (seconds)

According to the information provided in this question, Heather and Matthew spend 60seconds to travel a distance of 90 metres. This means that t = 60s, d = 90m

Hence,

Speed = 90/60

Speed = 3/2

Speed = 1.5m/s.

Explain how water is distributed in the body intracellular and extracellular such as plasma, lymph and intercellular

Answers

Answer:

The total volume of water corresponds to 60% of body weight. This volume is divided into two large compartments, the intracellular and the extracellular. The extracellular compartment is subdivided into plasma and interstitial fluid, with a volume ratio of approximately 1: 3. Regulation of intracellular volume is achieved in part by regulating plasma osmolality through changes in water balance.

Explanation:

Water is distributed in our body in different aqueous compartments, which are separated by cell membranes: intracellular fluid and extracellular fluid, which in turn includes interstitial fluid and plasma. Osmotic forces are the fundamental determinant of the distribution of water in the body, water can freely cross almost all cell membranes, and as a result the body fluids are kept in an osmotic balance, since the osmolality of the intra and extracellular fluid is the same. Intracellular fluid makes up about 40% of body weight: 28-42L of body fluid is within cells. Extracellular fluid constitutes about 20% or about 14 liters in a normal adult, all the fluids outside the cells. Plasma is the non-cellular part of the blood and it continually exchanges substances with the interstitial fluid through pores of the capillary membranes that are permeable to almost all the solutes in the extracellular fluid except for proteins. The distribution of the liquid between the intra and extracellular compartments is determined by the osmotic effect of the smallest solutes (Na, cl ...) that act through the cell membrane, since the cell membrane is very permeable to water and impermeable to ions small, water moves rapidly through the cell membrane, and the extracellular fluid remains isotonic with the extracellular fluid.
