how can natural selection account for the long tongues of butterflies?

Answers

Answer 1

Answer:

Because butterflies with longer tongues were better equipped to eat nectar from inside flowers, and so it was easier for them to eat and grow. So they were better quipped to survive than those with shorter tongues.

what is the difference between the way that saprotrophs and detritivores digest their food

Answers

Answer:

Externally

Explanation:

Usually, detritivores are mostly animals, while saprotrophs are mostly fungi. Furthermore, detritivores consume lumps of dead organic matter separately, while saprotrophs absorb chemically digested food. Saprotrophs digest their food externally, whereas detritivores do it internally in the digestive system.

200g of water at 90degree Celsius is mixed with 100g of water at 30 degree Celsius. What is the final temperature (C of water =4.2jkg-1 k-1​

Answers

Answer:

70 °C

Explanation:

Since heat lost by 200 g of water = heat gained by 100 g of water

-mc(T - T') = m'c(T - T")

where m = 200 g,T' = 90°C, m' = 100 g,T" = 30°C and T = final temperature of mixture, c = specific heat capacity of water = 4.2jkg-1 k-1​.

Substituting the values of the variables into the equation, we have

-mc(T - T') = m'c(T - T")

-200 g(T - 90 °C) = 100 g(T - 30 °C)

(T - 90 °C) = 100 g(T - 30 °C)/-200 g

(T - 90 °C) = -0.5(T - 30 °C)

T - 90 °C = -0.5T + 15 °C

collecting like terms, we have

T + 0.5T = 90 °C + 15 °C

1.5T = 105 °C

T = 105 °C/1,5

T = 70 °C

Identify the bonds formed between RNA nucleotides by RNA polymerase.

A. Ester
B. Glycosidic
C. Peptide
D. Phosphodiester​

Answers

Answer:

D. Phosphodiester​

Explanation:

Just as the DNA polymerase serves as a catalyst in the replication of the DNA, so does the RNA polymerase speed up the formation of the RNA. RNA polymerase performs its function of linking nucleotides when the phosphodiester bonds are formed in the 5' to 3' sequence. Nucleoside triphosphate precursors such as the Adenosine triphosphate, Cytosine triphosphate, and Guanosine triphosphate serve as the substrates that allow the formation of the RNA molecule.

When the RNA polymerase unwinds the double helix structure of the DNA found before the active site where the polymerization will occur, substrates can then pair themselves in a complementary form.

▪ Identify the bases used in DNA and RNA and how they pair – classify
each as a purine or pyrimidine

Answers

Answer:

DNA has a double- helix structure which means it has two strands. The DNA strands are made from sugar (Deoxyribonucleic), phosphates and nitrogenous bases. There are 4 nitrogenous bases, 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. The pyrimidine bases are Thymine and Cytosine. DNA gives our genes.

RNA is a single strand unlike DNA. The strands are made from sugar (ribonucleic), phosphate and the nitrogenous bases. There are 4 nitrogenous bases 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. However, the 2 pyrimidine bases are Uracil and Cytosine. The function of RNA is to contribute to releasing proteins based on our rRNA and tRNA and mRNA. This process is known as RNA and transcription.

Fungi are heterotrophs and, like animals, obtain their carbon and energy from other organisms.

Answer:

Fungi are a kingdom of mostly microscopic organisms that are closely related to animals. They include spore-producing organisms such as mushrooms, yeast, and molds. Fungi are almost always invisible to the naked eye. Fungi are made up of masses of tubular filaments called hyphae that penetrate and absorb nutrients from the substrates on which fungi grow. Some fungi have extensive networks of hyphae that enable the fruiting body of the fungi to grow very large, such as many species of the shelf, or bracket, fungi

Compare and contrast suspension feeding and deposit feeding-

Answers

Answer:

Suspension feeding involves collecting food particles like small organisms, organic matter, detritus which are suspended in water, often using some form of filtration.

Suspension feeders catch food or organic material from the water using tentacles or spiny arms

where as

Deposit feeding involves feasting on detritus and organic matter that have settled on the ocean floor.

Deposit feeders pass sand, mud, water or sediment into their mouths using mucous-covered tentacles or arms etc.

Explanation:

Suspension feeding ingests the food particles which are suspended in water, while deposit feeding ingests sediments and aquire foods.

What do you mean by Deposit feeders?

Deposit feeders may be defined as those aquatic organisms that forage on organic matter that settled down on the bottom.

Suspension feeding maintains the water quality in the aquatic environment, while deposit feeding enhances oxygen level and nutrient cycling.

Suspension feeding occurs similarly to filter-feeding that only ingests suspended particles. While deposit-feeding ingests the deposited particles like detritus, organic matter, etc.

Therefore, it is well described above.

The real length of one villus is 0.8 mm
Calculate the image length if the villus is viewed at a magnification of x20

magnification = size of image / size of real object

Answers

Answer:

Explanation:

Re arrange formula=Size of image=Magnification*size of real image

0.8mm*20=16mm

The image length will be "16 mm". A further explanation is below.

Given:

Magnification,

20

Size of real image,

0.8 mm

As we know the formula,

→ [tex]Magnification = \frac{Size \ of \ image}{Size \ of \ real \ image}[/tex]

or,

→ [tex]Size \ of \ image=Magnification\times Size \ of \ real\ image[/tex]

By substituting the values, we get

→                         [tex]=20\times 0.88[/tex]

Answers

Answer:

Unicellular prokaryotes that live in dust: Eubacteria

Unicellular eukaryotes that line in pond water: Protista  

Multicellular eukaryotes that live all over the planet and consume food: Anamalia  

Unicellular prokaryotes that live in volcanic ash: Archaebacteria  

Multicellular eukaryotes that have cell walls and are heterotrophic: Fungi  

Multicellular eukaryotes that have cell walls and are autotrophic: Plantae

Explanation:  

Prokaryotic organisms can be classified into two groups: Eubacteria and Archaebacteria. Eubacteria (i.e.,“true” bacteria) are unicellular prokaryotic microorganisms that live in normal environmental conditions. On the other hand, Archaea (Archaebacteria) are prokaryotic older organisms that thrive in extreme conditions (in this case, volcanic ash). Moreover, eukaryotic organisms can be classified into four kingdoms: Protista, Plantae, Fungi and Animalia. Protista are unicellular eukaryotes that live in different aquatic environments (i.e., oceans, ponds, streams, etc). Animals are multicellular, mobile, heterotrophic (i.e., organisms that cannot produce its own food) organisms whose cells lack walls. Fungi are heterotrophic organisms that acquire their food by absorbing dissolved organic compounds, whose cells have cell walls (but they lack chloroplasts). Finally, plants are multicellular autotrophic (i.e., organisms that produce their own food) organisms whose cells contain walls and chloroplasts (to produce food by photosynthesis).
