placentals and marsupials are two groups of mammals. placentals are more closely related to each other than they are to any othe

NeX [460]

Due to convergent evolution placental mammals (Wolf) are closely related to marsupial wolves (Tasmanian wolf). No, the tree is wrong.

What is convergent evolution?

It is the presence of similar features in animals of different lineages. The structures in these animals have similar functions but are absent in the common ancestors hence they are analogous structures not homologous.

Such convergence of functional, morphological, and structural traits from phylogenetically unrelated species may be a result of random mutation due to selection pressure.

Here, the Tasmanian wolf (marsupial wolf) and wolf (placental mammal) have several morphological similarities but they have unrelated ancestral lineages. Hence they show convergent evolution. These two subclasses of mammals have adapted to a specific food source, locomotor ability, or environment in similar ways.

Hence, the placental wolf and Tasmanian wolf exist sharing the same habitat in different continents former in Asia and the latter in Australia because these two show convergent evolution.

Chlorophyll molecules donate electrons to an electron acceptor ____. See Section 10.2 (Page 214) . View Available Hint(s) Chloro

Inessa [10]

Answer:

Chlorophyll molecules donate electrons to an electron acceptor in the reaction center.

Explanation:

Light reaction of photosynthesis takes place in the reaction centre. Light reaction may comprises of several proteins such as pheophytin, chlorophyll and quinones which act as light absorbing molecules.

The light reaction is the core of photosynthesis that produces ATP and NADPH to carry out the dark reaction for the production of high energy carbon molecules. During light reaction light photons are captured by photosystems such as photosystem I and II of chlorophyll in green plants. This photon cause the excitation of electron that flows through the electron transport chain from higher potential to lower potential and energy released by it is utilized for creating the gradient potential of H+ ions across the membrane. This gradient potential difference of H+ ions is used for the production of ATP through ATP synthase complex.

So chlorophyll molecules donate electrons to electron acceptors through the excitation of electrons from light photons in the reaction center.

Please place the following vessels in the correct order to represent the arterial circulation leading up to the glomerulus.

Ymorist [56]

The following vessels are connected as below:

aorta ->renal arteries ->segmental arteries ->interlobular arteries ->arcuate arteries ->cortical radiata ->afferent arteries ->glomerulus.

1) aorta : arises from heart which carry blood from heart to the rest of the body

2) renal artery :it arises from the aorta which carry blood to kidney .it carry unfiltered blood .

3)segmental arteries : it arises from renal artery .it has 5 branches or segments.

4)interlobular arteries : it arises from segmental arteries. the interlobular arteries pass directly outward between the medullary rays to reach the fibrous tunic ,where they end in the capillary network of this part.

5)Arcuate arteries: it arises from interlobular arteries .it is also known as arciform arteries, are vessels of the renal circulation. they are located at the border of the renal cortex and renal medulla.

6) cortical radiata: it arises from arcuate arteries.

7) afferent arteries: it arises from interlobular arteries and also connects to glomerulus. they are a group of blood vessels that supply the nephrons in many excretory systems .they play a important role in regulation of blood vessels.

8) glomerulus : it connects from afferent arteries.it is the filtering unit of kidney ,is a specialised bundle of capillaries that are uniquely situated between two resistance vessels.

Disclaimer: the given question is incomplete means it contains incomplete data .the correct question is given below.

Question: Please Place The Following Vessels In The Correct Order To Represent The Arterial Circulation Leading Up To The Glomerulus. Aorta Interlobar Artery Segmental Artery Afferent Arteriole Cortical Radiate Renal Artery Arcuate Artery Glomerulus
