how to identify oxygen and carbon dioxide?

Answers

Answer 1

Answer:

Place a glowing splint in the test tube, and if it reignites, it could be oxygen. Place a burning splint into a test tube, and if it goes out, it could be carbon dioxide. Or, place carbon dioxide gas in limewater, and if it turns milky and gets chunks, it is carbon dioxide.

comparison mitosis meiosis purpose ? ? number of parent cells ? ?

Answers

Explanation:

mitosis has 1 stage and meiosis had 2 stages.

Mitosis produces diploid cells (46 chromosomes) and produces 2 identical daughter cellsMeiosis produces happiness cells (23 chromosomes) and produces 4 genetically different daughter cells

Answer:

Mitosis and meiosis are nuclear division processes that occur during cell division.

Mitosis involves the division of body cells, while meiosis involves the division of sex cells.

The division of a cell occurs once in mitosis but twice in meiosis.

Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.

Daughter cells resulting from mitosis are diploid (46 chromosomes), while those resulting from meiosis are haploid (23 chromosomes).

Daughter cells that are the product of mitosis are genetically identical. Daughter cells produced after meiosis are genetically diverse (genes swap during division).

Mitosis has 1 parent and meiosis produces 2 types of sex cells which fuse at fertilisation.

These kingdoms were later revised to exclude minerals and expanded to include animals, plants, fungi, protists, and bacteria. Which of the following best explains a reason for this change? (2 points)

Group of answer choices

As new organisms were discovered, new kingdoms were created to sort them based on ability to interbreed.

It was discovered that the organisms in each of the five kingdoms have a different method of obtaining nutrients and are therefore fundamentally different.

Technological advances led to the discovery of single-celled organisms and increased our understanding of relationships between organisms.

Genetic research led to the discovery that each of these five kingdoms has a unique evolutionary ancestor.

squirrels that have different fur colors

Answers

flowers that bloom in different months

Flowers that bloom in different months is an example of temporal isolaton.

What is temporal isolation?

Temporal isolation is a type of reproductive isolation that occurs when two or more species reproduce at different times, thereby preventing mating between them. This can happen in a variety of ways, such as when one species is active during the day and the other at night, or when they breed during different seasons.

Temporal isolation can lead to the evolution of new species because it prevents interbreeding between populations that would otherwise exchange genetic material. Over time, these isolated populations can accumulate genetic differences that make it increasingly difficult for them to interbreed, leading to the formation of distinct species that are reproductively isolated from one another.

Earth’s continents are constantly in motion because they sit on top of gigantic plates which float on Earth’s mantle.

a.
biomes
b.
plates
c.
atmospheric layers
d.

Answers

Answer:

a. biomes

Explanation:

Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.

An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.

Generally, the different continents on Earth are in a constant motion due to the fact that they're sitted on top of gigantic plates floating on Earth’s mantle.

Furthermore, the Earth’s core generate energy which also creates convection currents in the molten layer of the Earth, thereby, moving the plates.

Over an extremely long periods of time, the movement of these plates create new biomes.

In Ecology, a biome can be defined as a relatively distinct terrestrial region which is made up of animals, micrograms and plants, and it is typically characterized by similar environmental factors such as wind, relative humidity, rainfall, temperature, etc., irrespective (regardless) of where it occurs in the world.

I don't know why there are two CUAs, but if someone could please help. This is confusing for me. Please explain & no false answers. Thanks much in advance!

Answers

Answer:

CUA

Explanation:

Chances are your teacher accidentally put the same option twice and marked one of em incorrect. You infact selected the correct answer because CUA is correct.

DNA has 4 bases: ATGC (Apples on Trees = A - T, & Cows eat Grass = C-G)

RNA has 4 bases: AUGC  (RNA lacks the base T so A binds with U instead).

So for template strand GAT, the mRNA made from this codon has complimentary pairing based on RNA so G binds with C, A binds with U, and T binds with A.

A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU

DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine)  in a sequence.

Adenine always bonds with thymine, and guanine only bonds with cytosine. In RNA however, uracil is substituted for thymine instead. So, in transcription, adenine turns into thymine, and guanine turns into cytosine, and vice-versa.

Thus, A triplet of bases in a template strand of DNA is GAT, the corresponding codon for mRNA - CTU
