Lamarck's ideas on evolution were adopted by some Russian scientists, includingLysenko. Russian textbooks printed Lysenko's assertionthat workmen who develop strong muscles from working in the mines would produce children who would be born stronger. Which of the major elements of evolution by natural selection is violated by this assertion
Answer:
The acquired characteristics are inherited.
Explanation:
Lamarck was a French naturalist and biologist. Lamarck was considered to be the early proponent who occurred the biological evolution. He was will known all over the world as early evolutionists.
Lamarck believed that the living things grow directly in the upward direction from a simple to a more complex form.
In the context, the ideas on the evolution were adopted by the Russian scientist which includes Lysenko. The Russian textbooks printed the assertion of Lysenko assertion that workmen develops a strong muscles those who are working in the mines that would produce strong children.
Bu this assertion, it violated the acquired characteristics that are inherited.

Malaria is a disease that kills over 800 000 people each year. What causes malaria and how is it spread? What drugs are used to treat this disease and why should Canadians be concerned about the spread of malaria worldwide?
Answer: Usually, people get malaria by being bitten by an infective female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken from an infected person.
When the genotype consists of a dominant and a recessive allele, the phenotype will be like _________ alllele.
Answer:
dominant
Explanation:
It dominant because when a dominant allele is present it will always take that phenotype for example if being tall is dominant and short is recessive and the person has the genotype of Tt that person will be tall because that big T is there.
Droughts occur due to climate change and elevated temperatures, which in turn may lead to other consequences as well. Imagine that a wildfire happened in the nature reserve. Predict what would happen if such an environmental shift that is so extreme and rapid
hits the nature reserve and the population of deer mice does not have time to adapt. Propose a possible solution for this problem.
Answer:
Research shows that changes in climate create warmer, drier conditions. Increased drought, and a longer fire season are boosting these increases in wildfire risk. ... Changes in climate add to these factors and are expected to continue to increase the area affected by wildfires in the United States.
Organelles are specialized structures that perform important cellular functions; they are structures you can generally see only under a microscrope. Which of the organelles below would you expect to find in all living cells?
A) cell membrane
B) cell wall
C) DNA
D) Cytoplasm
E) Nucleus
F) Chloroplasts
Answer:
I think D which is the cytoplasm

because it is not specific with cell is this off so cytoplasm is there in both the animal cell and plant cell
Adults produce gametes through a type of cellular reproduction called mitosis. The process of a sperm cell and an egg cell fusing together is called fertilizationand produces a zygote. As a zygote undergoes rapid cell division to develop into an embryo, fetus, and eventually baby, the type of cellular reproduction being used is . As a baby grows into an adult, the type of cellular reproduction used is mitosis.
Answer:
Mitosis.
Explanation:
Mitosis is the type of cellular reproduction which is used in order to develop an embryo, fetus, and eventually baby. In mitosis type of cell division, the parent and mature cells divides into two daughter cell. This type of cell division occurs in somatic or body cells whereas meiosis type of cell division occurs in the sex cells which produces four daughter cells from a single parent cell.
Do you think if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions?
Answer:
yea
Explanation:
cause our climate conditions changes everyday depends on the atmosphere at that time so if there fire in a forest all the animals there have to adapt to the smoke.
Yes, if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions.
Why plants and animals will change their features?
Plants and animals are fundamentally different in many ways, but one of the most obvious is in how they deal with temperature.The climatic niche of a species reflects where it can live.A species with a wide climatic niche can range widely across many different conditions and may be especially resilient to climate change.Different sets of plant and animal species tend to occur at different elevations, which differ in temperature and precipitation.

In non-muscle cells, a small increase in the cytosolic concentration of Ca2 can have a dramatic effect on several physiological processes. The presence of a specific protein in the cytosol, however, activates a Ca2 ATPase that serves to return these elevated cytosolic Ca2 levels back to basal levels, thereby maintaining the cell's normal physiology. Which protein is directly involved in activating this Ca2 ATPase
Answer:
calmodulin
Explanation:
The calcium-modulated protein (calmodulin) is a calcium-binding receptor protein that modulates contractile proteins (i.e., actin and myosin proteins) of the skeletal muscle and non-muscle cells (e.g., platelets). Calmodulin binds to calcium ions (Ca2+) and subsequently activates a number of Ca2+ dependent enzymes (e.g., kinases or phosphatases), which finally activate/deactivate proteins in the calcium signal transduction pathway. Ca2+-ATPase pumps in the membranes of eukaryotic cells release Ca2+ from the cytoplasm and they are autoinhibited by low Ca2+ levels, while calmodulin-binding releases this autoinhibition and thus activates the pumps. In non-muscle cells such as platelets, calmodulin also mediates Ca2+ control of actin-myosin interaction by phosphorylation of the myosin light chain (MLC).

What's the differences between species richness management approach and indicator species management way?
Answer:
Both have different function.
Explanation:
The main difference between species richness management approach and indicator species management way is that in species richness management we perform activities that allows increase in the population of species while on the other hand, indicator species are the organisms that provides information about the environment that is present in that ecosystem. Both has differences in their functions and their actions.

Answer:
To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination.

An epistatic allele in labrador retrievers ensures that ee lab pups are yellow. Two other alleles control coat color, where black is dominant to brown. What portion of yellow pups would you expect from a parental cross where one parent was yellow (Bbee) and the other was heterozygous
Answer:
1/4
Explanation:
Epistasis is defined as a phenomenon in a genetics where the effect of the gene mutation which dependent on the absence or the presence of the mutation in more than one genes.
In the context, an epistatic allele in the Labrador retrievers which ensures the ee lab pups that are yellow and the two other alleles which control coat color are black that is dominant to the brown.
Thus, 1/4 portion of the yellow pups would expect from the parental cross where one of the parent is yellow (Bbee) and the other is heterozygous.
Thus the answer is 1/4.
