Answer:

One or more members in the rest of the chain could cease to exist too.

The finding that successful species were often more successful than faster-evolving competitors would most directly support the claim that previous species success, not evolution rate, is the most accurate predictor of survival.

The finding that would most directly support the underlined claim—that previous species success predicts species survival much more accurately than speed of adaptation—would be the one stating that 'Successful species tended to remain more successful than more quickly-evolving competitors'. This statement gives direct evidence to the fact that the success of a species in the past is a good predictor of its future survival, regardless of how fast it may be evolving.

This is not to say that the evolution rate isn't important at all. It's just that, according to the 2019 study published in Nature Ecology & Evolution cited in the question, the connection isn't clear or strong enough to be considered a reliable predictor of species survival.

Answer:

Accumulation of lactic acid

The anaerobic cellular process is a type of respiration that occurs in the scarcity of oxygen. Lactic acid gets accumulated in anaerobic respiration during vigorous exercise. Thus, option A is correct.

Anaerobic respiration is a cellular process where the organic and the biological fuel are broken and oxidized through the electron transport chain in the cytoplasm of the cell.

The anaerobic cellular process lacks the use of oxygen so to produce energy like ATP and lactic acid accumulation due to the high energy demand during vigorous exercise.

In the anaerobic cellular process, carbon dioxide and water are formed as a byproduct along with lactic acid and ATP. Lactic acid is formed from the breakdown of glucose and glycogen.

Therefore, in option A. in the anaerobic cellular process, accumulation of lactic acid occurs.

Answer:

Early hominin fossils are hard to find for several reasons. First, the geological processes of erosion and sedimentation can destroy or bury fossils, making them difficult to access. Second, early hominins likely had low population densities, so the chances of fossilization were relatively small. Finally, the habitats in which early hominins lived, such as forests and savannas, are not conducive to fossil preservation, as the organic materials are quickly decomposed by microorganisms and the elements.

The plants exhibit pharmacological significance due to their alkaloid content, which can have potent effects on the nervous system and various bodily functions.

Family Solanaceae, commonly known as the nightshade family, is a diverse group of flowering plants characterized by several key features. The floral formula of Solanaceae is typically represented as (5) K (5) C(5) A(2+2) G(2), indicating five sepals, five petals, five fused stamens (with two longer and three shorter ones), and a superior ovary composed of two fused carpels. The floral diagram represents a radial symmetry with overlapping sepals and petals, and the stamens and pistil positioned in the center.

Solanaceae encompasses many medicinally important plant species. Two notable examples are:

Atropa belladonna: Also known as deadly nightshade, Atropa belladonna contains alkaloids such as atropine and scopolamine, which have various medical uses. These compounds have anticholinergic properties and are used in medicine to dilate pupils, treat gastrointestinal disorders, and relieve bronchial spasms.

Answer:

See the answer below

Explanation:

An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.

Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons.

The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.

Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.

The wrong statement concerning blood vessels is (b) smooth muscle surrounds capillaries.

The blood vessel is classified into arteries, veins, and capillaries. Each of them has a different characteristic that supports its function.

Arteries contain more muscle than veins is true. Arteries and veins are made of 3 layers (tunica intima, media, and adventitia), but arteries contain more muscle than veins since arteries are always under high pressure.

The smooth muscle surrounding capillaries is wrong. Smooth muscles are the most abundant cell in the blood vessel wall. They can be found in all blood vessels except capillaries and pericytic venules.

Valves are found in veins but not arteries are true. Veins have valves to avoid blood from moving backward.

Discontinuous capillaries create sinusoids is true. There are 2 types of capillaries. The first type is continuous capillaries which is the smallest blood vessel and the second type, is discontinuous capillaries or sinusoid. These have larger gaps and pores and are found in the liver, spleen, and bone marrow.

Thus, options A, C, and D are correct except for B because capillaries don't have smooth muscle.

Answer:

1.2 mL

Explanation:

This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.

Recall that: number of moles = mass/molar mass or molarity x volume.

Hence, for the dilution principle:

              initial molarity x initial volume = final molarity x final volume.

In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.

Initial volume = final molarity x final volume/initial molarity

                       = 0.1 x 12/1 = 1.2 mL

It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.

The volume should be 1.2 mL

It should be agreed that the no of moles prior to the dilution should be equivalent to the no of moles after dilution

We know that

number of moles = mass / molar mass or molarity x volume.

According to the above principle, we can say that

initial molarity x initial volume = final molarity x final volume.

So,

initial molarity of NaOH = 1 M,

initial volume = ?,

final molarity = 0.1 M,

And,  final volume = 12.0 mL.

So,

Initial volume = final molarity x final volume/initial molarity

= 0.1 x 12/1

= 1.2 mL

Hence, The volume should be 1.2 mL

Explanation:

The biodiversity index of the one-acre lot observed is 0.054. Based on the given information, first area is not biologically diverse as its biodiversity is lower than the second lot.  Reasons suppressing biodiversity in the first acre counted could be fewer food sources, overexploitation of the natural environment, and habitat loss.

Diversity refers to the measure of the number of different species in a biotic community. A biodiversity index refers to a scale of the diversity of species at the study site. It is commonly used for estimating the complexity, stability, and thus general health of an ecosystem.

The biodiversity index is determined by dividing the number of species in the area by number of individuals in the area. In the given case, the number of species in the area is 6 and the total population is 110. Hence, the biodiversity index is 6/110 = 0.054. It indicates that there is low diversity in the area.

If you collected the same information for a second square acre 10 miles away and determined that acre to have a biodiversity index of 0.37, the first area is not considered biologically diverse as the biodiversity index is higher in the second area than the first area. A high index value indicates a stable site with many different niches and low competition while a low index value indicates a site with few potential niches where only a few species dominate.

The possible reason which is suppressing biodiversity in the first acre counted could be fewer food sources, overexploitation of the natural environment, and habitat loss.
