What is the approximate age of the ash footprints at Laetoli? (Hint: what is the radiometric age of Laetoli?)

Answers

Answer:

The correct answer is - 3.66 million years ago.

Explanation:

Laetoli, located on the Eyasi Plateau which is known for the remains or footprints of the oldest hominin that were formed and preserved by a series of events -  a volcanic eruption, a rainstorm, and another ashfall.

The remains and footprints were discovered at 1978 and are attributed to Australopithecus afarensis. The age of this remaining footprint can be estimated with the help of the radiometric method of the remains which tells that the footprints are 3.66 million years ago formed.

Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease

Answers

Answer:

Increases.

Explanation:

The pH of the intermembrane space increases as the poisoning of cyanide occurs. After cyanide poisoning, the electron transport chain can stop pumping of electrons into the intermembrane space. The pH of the intermembrane space would increase, the pH gradient would also decreases, and ATP synthesis would stop to occur. The pH of the intermembrane space is neutral i.e. 7 but due to cyanide it move towards basic.

Answer:

Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, the pH of the intermembrane space becomes more basic. The electron transport chain can no longer pump hydrogen ions into the intermembrane space and ATP synthesis stops.

Most body water comes from:moisture absorbed through the skin.fluids we drink.the food we eat.metabolism.

Answers

Answer:

fluids we drink.

Explanation:

Most body water comes from fluids we drink such as water, juices etc. Our body obtains water by absorbing it directly from the digestive tract. A small amount of water is produced in the metabolism of food particles. Our body loses excess amount of water by excreting it in the form of urine from the body. Kidney is the organ that filters waster materials and excess water from the blood and remove it from the body.

What is the difference between food chains and food webs?

1. Food webs show the flow of energy from producers to consumers, and food chains show the flow of energy from consumers to producers.

2.Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

3.About ten percent of the energy is passed on to the next trophic level in food webs, but in food chains, about ninety percent is passed on to the next trophic level.

4.Heat is lost when energy is passed on to the next trophic level in food chains, but in food webs, heat is not lost when energy is passed on to the next trophic level.

Answers

Answer:

2. Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

Explanation:

A food chain is a single chain representing who eats whom in a system of organisms. A food web is a system of food chains, involving overlapping pathways of different foodchains.

Answer:

2.Food chains show a single path of energy in an ecosystem, and food webs show overlapping pathways of energy in that ecosystem.

Explanation:

A food chain shows only a targeted path, while a food web shows a more realistic path. See attached photos.

First picture: Food Chain: Notice how it only shows one path from producer to tertiary consumer.

Second picture: Food Web: Notice the many pathing that connects for certain organisms in the food web. It shows a more realistic distribution of energy in a real world scenario.

They form arbuscular mycorrhizae.

Explanation:

Glomeromycota form arbuscular mycorrhizae and they do not undergo sexual reproduction.

Glomeromycota is one of the divisions of fungi that can be found in soils where they form symbioses(association where both glomeromycota and the plant benefits) with the roots of the plants. They can also be found in wetlands. An example of glomeromycota is Acaulospora.

They are also called mycorrhiza. They reproduce through asexual reproduction.

A scientist was studying a population of elephants. The first year, he counted a population of 80. Over the next eight years, the population's numbers were 94, 100, 103, 110, 125, 120, 125, 120. What appears to be the carrying capacity for this population? 120 124 125 126

Answers

Answer:

125

Explanation:

The correct option would be 125.

The carrying capacity of a particular environment generally refers to the maximum number of individuals of a particular species that the environment can support at a particular time based on the resources it has. Hence, the maximum population of a species will normally oscillate around the carrying capacity of the environment where it is found.

In the case of the elephants in the illustration, the maximum population recorded was 125. The population decreased from this value at some point only to increased back to it later.

Hence, the carrying capacity for the elephant is 125.

why do wild plants need to reproduce sexually as well as asexually ?

Please answer correctly​

Answers

Answer:

Wild plants would need to reproduce sexually so that there can be variation throughout the species to reduce the number of plants being at risks to certain diseases if the environment is changing. However, the wild plants need to produce asexually if the environment is stable.

Wild plants need to reproduce sexually as well as asexually in order to create variation within a species and lower the number of plants that are susceptible to specific illnesses in a changing environment.

What are wild plants?

Wild plants would need to reproduce sexually. However, if the environment is stable, wild plants must reproduce asexually. Since male and female gametes are not mixed, asexual reproduction produces plants that are genetically similar to the parent plant and increases survival.

A seedling formed from a seed matures more slowly and is less robust than a cutting or bud is taken from an older plant.

Therefore, in order to diversify within a species and reduce the number of plants susceptible to specific diseases in a changing environment, wild plants must reproduce both sexually and asexually.

If you are interested in the evolutionary relationship of animals that have four limbs, which of the following would be the outgroup? Group of answer choices Sharks Ray-Finned Fish Amphibians Crocodiles Dinosaurs

Answers

Answer:

First outgroup → Ray-Finned FishesSecond outgroup → Sharks

Explanation:

The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.    

Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.

To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.  

In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.

From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,

First outgroup → Ray-Finned FishesSecond outgroup → Sharks

Just after they taste a sweet liquid, mice are injected with a drug that produces an immune response. Later, the taste of the sweet liquid by itself triggers an immune response. This best illustrates

Answers

Answer:

This question lacks options, options are:

a) classical conditioning

b) observational learning

c) spontaneous recovery

d) operant conditioning.  

The correct answer is a.

Explanation:

The classical conditioning theory derives from the experiments of the Russian physiologist Ivan Pavlov, he hypothesized that when any stimulus predicts the occurrence of another stimulus that triggers an automatic response, that first stimulus would acquire the ability to trigger that response, in other words , is a type of learning according to which an originally neutral stimulus, which does not provoke a response, becomes able to provoke it thanks to the associative connection of this stimulus with the stimulus that normally provokes said response. The conditioning of the immune response is built on the same principles of the classical conditioning paradigm described by Ivan P. Pavlov in which an environmental stimulus that by itself does not produce any immune reaction (conditioned stimulus), is associated with substances that stimulate or they suppress immune function (unconditioned stimulus), and finally, by presenting the conditioned stimulus alone, trigger the appropriate immune response.

Answers

Answer:

The force of friction between the two surfaces will increase if the two surfaces are pressed harder against each other. Heavy box will press the floor surface harder as compared to the lighter box. That means the force of friction will be more between the heavier box and surface than between the lighter box and surface. Thus, larger force will be needed to push the heavier box than to push the lighter one.
