what is combination reaction?

Answers

Answer 1

COMBINATION REACTION:

Combination reaction is a reaction where two or more elements or compounds combine to form a single compound. Such reactions are represented by equations of the following form: X + Y → XY. The combination of two or more elements to form one compound is called combination reaction

An example could be lithium reacting with sulfur to give lithium sulfide. When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide.

How do living organisms maintain homeostasis within their bodies?

Answers

Answer:

The body regulates those levels in an example of homeostasis. When levels decrease, the parathyroid releases hormones. If calcium levels become too high, the thyroid helps out by fixing calcium in the bones and lowering blood calcium levels. The nervous system helps keep homeostasis in breathing patterns.

When we talk about soil depletion, which soil horizon are we talking about? Thank you

Answers

Answer:

Surface Horizon (A)

Nutrient depletion of soils is a widespread soil degradation phenomenon that occurs as a consequence of soil erosion (it is the topsoil in which generally most soil nutrients are present that erodes fastest) but also because of poor management practices, such as slash and burn and other subsistence agricultural.

Which statement best explains why the classification
schemes of taxonomists have changed over time?
A. New technology like DNA sequencing allows scientist to have a more accurate genetic evolutionary history
B. New information about the genetics of species is being discovered.
C. Molecular biology has provided more detailed evidence for the relationships
between organisms.
D. All of the above

Answers

Answer:

D.

Explanation:

Sana tama kase feel ko pang

Classification of organisms is defined as dividing living beings into different kingdoms based on their genetics, traits, and other features.

Why did Classification Schemes of taxonomists change?

Taxonomists arrange and divide the organisms based on the DNA, traits, and features of the living organisms.

The advancements in technology led the taxonomists to have more information on genetic lineage and arrange them accordingly.

Introduction and discoveries of new species, their genetic make-up, and traits also contribute to the change of classification system.

Molecular biology, cellular level studies, and genetics of species have contributed to the classification of organisms.

Thus, the given statements about the classification of organisms are correct.

Biology.

Answers

Answer:

You can separate them according to the shapes of their beaks.

Some have longer, pointier beaks whilst others have flat and short beaks.

This is because they eat different things: seeds vs worms and insects.

This means that the shape of their beak is an adaptation (it enables their survival) because it makes it easier for them to consume food.

This is known as occupying different niches in the habitat, because even if they all live in one area, they will eat different things, meaning that they will always have enough food to survive.

Here are some fact about sharks that i found cool

#1

Possibly one of the most evolved sharks today are hammerhead sharks. They have an advanced sensory system and a body shape that has adapted to hunt specific prey

#2

Sharks may be one of the most important species on Earth. They have been maintaining our oceans for over 400 millions years.

#3

Sharks have evolved and changed much over millions of years. However many sharks today still share some of the features as sharks from millions of years ago.

#4

Sharks have been in our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age.

#5

Sharks have survived five massive planet extinction events. These extinction events killed most life on earth and the last one around 65 million yeas ago killed the dinosaurs.

#6

There are over 500 species of shark.

#7

It is believed that each whale shark's pattern is unique, like a human's fingerprint.

#8

Sharks do not have bones. Instead, they have cartilage, that's what makes up human noses and ears

#9

According to the Smit.hsonian, there are over 500 known shark species, though many are endangered or declining due to various factors like overfishing.

#10

Your odds of getting attacked and killed by a shark are 1 in 3,748,067. In a lifetime, you are more likely to die from fireworks or lightning. Whereas over 100 million sharks are killed every year by humans.

#11

Whale sharks are the world’s biggest fish.

#12

Sharks mature slowly and reach reproductive age anywhere from 12 to 15 years.

#13

Hammerhead sharks' eyes are on the sides of their heads, so they have nearly a 360-degree sight line. Their panoramic view of the undersea world is inhibited by two blind spots, one in front of the snout and the other directly behind the head.

#14

Sharks predate the dinosaurs by 200 million years.

#15

Great whites can detect one drop of blood in 25 gal (100 L) of water and can sense even tiny amounts of blood in the water up to 3 mi (5 km) away.

Photosynthesis-

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. Photosynthesis occurs in the chloroplast of a plant, which contains chlorophyll. In order for photosynthesis to take place, it needs to have water and carbon dioxide, the two very important raw materials necessary for this process. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as this energy-rich molecule known as glucose. Oxygen the by product of photosynthesis is inhaled by heterotrophs which aids in cellular respiration and other internal processes and then exhales carbon dioxide. ... In like manner, carbon dioxide passes from blood to the alveoli and exhaled after

What is the structure of a virus?

Answers

Answer:

The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

A virion consists of a nucleic acid core, an outer protein coating or capsid, and sometimes an outer envelope made of protein and phospholipid membranes derived from the host cell. The capsid is made up of protein subunits called capsomeres. Viruses may also contain additional proteins, such as enzymes

B)
ccdd is not possible as an outcome of this cross,
All of the offspring will show the dominant trait for the allele.
D)
Only half of the offspring will show the dominant trait for the Dallele.
E)
All of the offspring will be heterozygous and will display the dominant
traits

Answers

Answer:

A,B,C,D

Explanation:

Since one parent is CC, there is no way to get cc as an outcome from this cross. However, there is also no way that all of the offspring will be CcDd, which is heterozygous for both traits. Therefore, this is the only answer choice that is incorrect.

As per observation about the  two individuals that have the following genotypes: CCDd and Ccdd the cross are options: a,b,c,d.

Since one parent is CC, there may be no manner to get cc as an final results from this cross. However, there may be additionally no manner that every one of the offspring could be CcDd, that is impure breed for each traits.

how does the coconut plant adapt in goa​

Answers

Goa's climate is tropical, hot all year round, with a long and sunny season, which runs roughly from mid-October to mid-May, and a rainy season due to the south-west monsoon, more or less from late May to early or mid-October, and characterized by stuffy weather, cloud cover and frequent rains, which occur almost daily .

The coconut seed is especially well adapted to increasing its range by the method of ocean dispersal. The seed floats when its outer layers dry out. The buoyant coconuts drift on ocean currents and end up on tropical beaches where they germinate and take root.

Coconut tree grows only in the tropical climate. This plant live on the sandy soil, requires a lot of sunlight and regular rainfalls. Coconut tree does not tolerate low temperatures and low percent of humidity.

so goa is one place which is suitable for growing coconut.
