Answer:
B. False
Explanation:
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. ... Functionally similar features that have arisen through convergent evolution are analogous, whereas homologous structures or traits have a common origin but can have dissimilar functions.

When new molecules are introduced to one isolated area of a solution, there will temporarily be a high concentration of those molecules in one area of the solution. What is the name for the spontaneous process of dispersing these molecules to create a uniform concentration throughout the solution?
1. osmosis
2. transport
3. filtration
4. diffusion
Answer:
4.Diffusion
Explanation:
Diffusion if the movement of particles from a region of high concentration (where there is many) to a region of low concentration (where there is less) until it is evenly distributed.
The picture below represents which
stage of photosynthesis?
A. Dark reactions
B. Calvin Cycle
C Glycolysis
D Light reactions
It represents Glycolysis, a key metabolic route that produces energy and generates precursors for the production of primary metabolites in plants. Thus, option (C) is correct.
Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
The first method of breaking down glucose to release free energy is called glycolysis .Two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water are produced during glycolysis.
Hence, the picture depicts the process of gylcolysis , stage of photosynthesis i.e option (c)

58. Which of the following Kingdoms contain multicellular organisms? *
Answer:
The answer is fungi.
what happens directly after metaphase
Answer:The third phase of mitosis, following metaphase and preceding telophase, is anaphase. Since the sister chromatids began attaching to centrosomes on opposite ends of the cell in metaphase, they're prepped and ready to start separating and forming genetically-identical daughter chromosomes during anaphase.
Explanation:
Answer:
The next phase is anaphase. The chromatids separate at the centromere. The spindle fibers begin to pull them to opposite sides of the cell.

Changes in global temperature and other Choose... conditions have effects on organisms and on the clades to which they belong. The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of a Choose... pattern. This pattern includes Choose... extinction, which tends not to disturb ecosystems, as well as Choose... extinction, in which ecosystems change drastically.
Answer:
larger macroevolutionary patterns.
extinction, in which ecosystems change drastically
Explanation:
The emergence, growth, and extinction of a large clade, such as the dinosaurs, is an example of larger macroevolutionary patterns. This larger macroevolutionary patterns occur due to climate change. Extinction of organisms in which ecosystems change drastically that leads to unfavourable environmental conditions which decreases the population to the extinction of organisms.

In the plasma membrane, the phospholipid heads Group of answer choices are hydrophilic and face inward, shielded from water. are hydrophobic and face outward toward the aqueous solution on both sides of the membrane. are hydrophobic and face inward, shielded from water. are hydrophilic and face outward toward the aqueous solution on both sides of the membrane.
Answer:
are hydrophilic and face outward toward the aqueous solution on both sides of the membrane
Explanation:
The plasma membrane is structurally made up of a phospholipid bilayer, which is amphipathic in natire. This means that the phospholipid layer of the plasma membrane consists of phosphate head that is water loving or hydrophilic in nature and a lipid tail that is water fearing or hydrophobic in nature.
Since the phosphate head is HYDROPHILIC, they face outward toward the aqueous (water) solution on both sides of the membrane. This allows the phosphate head to attract water molecules.

How does mining impact the enviorment
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
Answer:
Mine exploration, construction, operation, and maintenance may result in land-use change, and may have associated negative impacts on environments, including deforestation, erosion, contamination and alteration of soil profiles, contamination of local streams and wetlands, and an increase in noise level, dust

qué ventajas le trajo al ser humano el poder andar en 2 patas.
Answer:
The advantage that hominids had when they developed bipedalism is truly great. Walking on two legs instead of four allowed hominids to free up their arms. Using their arms they could now make tools, stretch trees, and use their hands for social communication. The development of bipedalism also allowed for long-distance walking and eventually endurance running. Bipedalism, basically, was a key step for hominids' "brains to grow".
[tex]{\sf{\boxed{\boxed{\tt\green{Las \: ventajas}}}}}[/tex]
La gran cantidad de ventajas que trajo el bipedalismo significó que todas las futuras especies de homínidos llevarían este rasgo. El bipedalismo permitió a los homínidos liberar completamente sus brazos, lo que les permitió hacerEnglish:

Answer:
The growth rate.
Explanation:
To determine the density of a rabbit population, one would need to know the number of rabbits and the growth rate of rabbit's population because both factors allow us to determined the population of rabbit in a specific region. If we know the existing population of rabbits in a particular area as well as the growth rate at which the rabbit population increases so we can find out the density of rabbit population in a specific time period.

What is Homologous evolution and Analogous evolution give its example !
Spam✔️
Homologous evolution means divergent evolution.
it is a type of evolution in which different species have common ancestor. for example if we take members of one species and put them in different environments then it is observed that there is some changes in the species according to environment
analogues evolution means convergent evolution
Answer:
Similar traits can be either homologous or analogous. Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale's front flipper are homologous to the bones in the human arm.
