Answers

Answer 1

Answer:

D, the fossil in the Cambrian period

Explanation:

there are time periods on the left side that go from youngest on the top and oldest on the bottom

Answer 2

In the labeled diagram the fossils comes from the oldest organism an index fossil from the Cambrian period is labeled at the point D. Thus, option D is correct.

What is the index fossil about?

Index fossils, which is also known as the key fossils or the guide fossils, are fossils of the organisms that are used to help determine the age of rock formations and sedimentary strata. Index fossils are typically chosen because they are easily recognizable, widespread, and existed for a relatively short period of time.

They are used as "markers" for specific time periods, and the presence or absence of certain index fossils can help scientists determine the relative age of rock formations.

In this scenario, the index fossil labeled A is from the Jurassic period, which lasted from about 201 to 145 million years ago. The index fossil labeled B is from the Permian period, which lasted from about 299 to 251 million years ago.

Therefore, In the labeled diagram the fossils comes from the oldest organism an index fossil from the Cambrian period is labeled at the point D. Thus, option D is correct.

If a cell has 24 pairs of chromosomes in its diploid state, how many
chromosomes will it have after Meiosis 2?
A. 12
B. 24
C.48
D. 6

Answers

Answer:

option A is correct that is 12

Explanation:

meiosis occur in two phases in first phase DNA replication occur and amount of DNA become doubled without any change in the chromosome number and two daughter cell (each 2 n)are formed.

now in stage 2 each daughter cell undergoes mitosis with the formation of two cells with half chromosomes(n)

now 2n=24

n=24/2 =12

after meiosis stage 1...........two daughter cell each with  24 chromosomes

stage 2 .............each daughter cell form two grand daughter cell each with 12 chromosomes

net result.......4 daughter cell each with 12  chromosome(assuming cell as a diploid cell)

If a cell has 24 chromosomes before cell division then the daughter cell resulting from the mitotic division will have 24 chromosomes while the daughter cell resulting from the meiotic division will contain 12 chromosomes each.

The answer is option A.

What are meiotic and mitotic cell divisions?

There are sorts of cell departments: mitosis and meiosis. most of the time whilst humans discuss “cellular division,” they suggest mitosis, the procedure of making new frame cells.

Find the weight of a pine tree that has a circumference of 14 inches and a height of 120 feet. Use the equation: W = b0 + b1(D2H)

Answers

Answer:

The answer is below

Explanation:

The weight of trees is calculated using the equation:

[tex]W=b_o+b_1(D^2H)[/tex]

Where W is the weight in tons, [tex]b_o \ and\ b_1[/tex] are constants , D is the diameter of the tree in inches and H s]is the height of the tree in feet.

The circumference = 14 inches. But circumference = 2πr, where r is the radius and π = 22/7. Therefore:

14 = 2(22/7)× r

14 = (44/7)×r

r= 14 × 7 / 44 = 2.23 inches

Diameter = 2r = 4.45 inches

[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381b_1\\Let\ us\ assume\ b_o = -34.671,b_1=1.859.\\Therefore\\W = -34.671+2381(1.859)\\W=4392 \ tons[/tex]

In a cladogram (a type of phylogenetic tree), clades are groups of related organisms. In the past, phylogenetic lists built clades using the idea of parsimony, that the pattern that uses the fewest evolutionary changes is the most likely to be correct. Today, with the use of computers and DNA sequences, the explanation that is thought to be the best is ___________ .

Answers

Answer:

one with the fewest number of genetic differences in the nucleotide sequence.

Explanation:

A cladogram is a diagram capable of showing the relationships among different species and/or group of organisms. In a cladogram, the root indicates the common ancestor, while internal nodes represent the common ancestors of each group. In consequence, this diagram can be used to establish evolutionary relationships in which the start branch points represent common ancestors shared by the organisms found in the 'branches'. Nonetheless, the length of the branches in the cladogram does not represent evolutionary distances among groups. In recent years, cladograms based on DNA sequencing data have been combined with morphological data to establish evolutionary relationships among species.

11. The governments of many countries have regulations
that are designed to prevent the accidental
introduction of nonnative insects into their countries.
This is because, in these new habitats, the nonnative
insects might
1) become food for birds
2) not survive a cold winter
3) not have natural predators
4) add to the biodiversity

Answers

4) add to the biodiversity.

this one is right. I’m sure. Hope it helps!

Answer:

The answer is 3. Not have natural predators.

Explanation:

Nonnative insects in new habitats mean that there are no predators there that eat them. This means that choice 1 will be eliminated. Now choice 2 also isn't it since if the insects do not survive a cold winter, there wouldn't be any nonnative insects in the habitats, causing no need to have strict regulations. Between choices 3 and 4, 4 doesn't make any sense. If it adds to a habitat's biodiversity, the ecosystem will benefit from it. However, the nonnative insects will harm the ecosystem, causing choice 4 to be eliminated. This means that only choice 3 is left. Choice 3 also makes sense since the nonnative species are also invasive species, having no natural predators in the new habitat. So, the answer is 3. Not have natural predators.

Vertical farming is the practice of growing local crops like fruits and vegetables with minimal resources by using high technological methods in a controlled environment.

Why vertical farming is important?

It has been said to be the future of agriculture in the UAE since they huge amount of goods and have to find ways to be self sustaining by boosting local production. Apart from being self sustaining, they also aim to provide safe and nutritious food.

The vertical garden is an agriculture concept for growing plants inside buildings or multi-story skyscrapers, often called farmscrapers, a term derived from the English skyscraper. In these buildings, which would function as large greenhouses, agriculture involves the use of technologies such as hydroponics to aid in plant growth. Some projects include the practice of livestock (especially poultry) on the lower floors.

describe classification as a work in progress discuss the characteristics of the three domains: Bacteria, Archaea, and Eukarya describe classification by cladistics summarize how molecular evidence reveals species relatedness identify the structures and shapes of viruses describe different types of viral infections

Answers

Answer:

Bacteria, Archaea, and Eukarya represent the three domains of life by which all living organisms are classified. This type of classification was coined by Carl Woese et al. (1990). Archaea and Bacteria represent different domains because Archaea is considered to have the evolutionary oldest phenotypic features, while Bacteria species have diacyl glycerol diester lipids in their membranes. On the other hand, the Eucarya domain is composed of organisms that possess a nuclear envelope (membrane).  

Cladistics is a biological method used to classify organisms into groups named 'clades'. In this type of classification, organisms are categorized according to the most recent common ancestor. In this regard, it is possible to find the most recent common ancestor by using nucleotide differences between taxa.

Viruses can be classified in a similar manner to the cellular organisms above described. Viruses are categorized according to morphological features, type of nucleic acid (DNA or RNA) by which they are composed, mode of replication, host organisms, etc. Viruses may also be classified according to the type of disease that they cause. There are viruses that cause chickenpox, rabies, influenza, old sores, Ebola, AIDS (HIV), Severe acute respiratory syndromes (SARS), etc.

Describe classification as a work in progress

Since it reflects the most current understanding of how living things are related, new discoveries can change the way living things are classified also something is always changing.

Discuss the characteristics of the three domains: Bacteria, Archaea, and Eukarya

Bacteria includes common bacteria, Eukarya includes the four kingdoms: plants, animals, fungi, and protists. Archaea includes some of the oldest organisms on the planet.

If capeland switches from producing 0 watermelons to producing 18 million tons of watermelons, what does it give up?

Answers

Answer:

Attached to this solution is an image of the complete question and data.

The correct answer is:

6 million pairs of shoes

Explanation:

From the diagram attached to this answer, the following data can be gotten:

Watermelons                   shoes

(Millions of tonnes)          (Millions of pairs)

0                                        15

8                                        14

14                                       12

18                                       9

20                                      5

21                                       0

From the pattern of the data shown above, we notice that as the production of one commodity increases, the other is given up (decreases)

Therefore, to find how much shoes are given up if Capeland switches from 0 watermelons to 18 million tons of watermelon, we will find the difference between the number of shoes produced at 0 and at 18 million tons of watermelon

at 0 watermelon; shoes = 15 million pairs

at 18 million tons of watermelon; shoes = 9 million pairs

Therefore, number of shoes given up = 15 - 9 = 6 million pairs

Hence, 6 million pairs of shoes are given up tp increase production of watermelon from 0 to 18 million tons

Answers

Answer:

C. A chlorine breaks off and forms a free radical

Explanation:

When CFCs are exposed to high levels of UV radiation in the atmosphere, the CFC molecule breaks into chlorine and forms free radicals.

These free chlorine radicals then reacts with ozone molecules and breaks the ozone atom (O3) to form chlorine monoxide and oxygen (O2) molecule.

CFCs are main cause of ozone depletion in the atmosphere.
