And object is 20 cm from the lens. The image from 6.66667 cm from the length. What is the focal length of the lens? Use the thin lens equation
Answer:
5
Explanation:
The object distance Is 20 I'm
The image distance is 6.666
Therefore the focal length can be calculated as follows
1/f = 1/20 + 1/6.66
= 6.66+20/133.2
= 26.66/133.2
1/f= 26.66/133.2
f = 133.2/26.66
= 4.99
= 5
Hence the focal length is 5

what did Galileo contribute to the field of microscopy
Answer:
In the late 16th century several Dutch lens makers designed devices that magnified objects, but in 1609 Galileo Galilei perfected the first device known as a microscope. Dutch spectacle makers Zaccharias Janssen and Hans Lipperhey are noted as the first men to develop the concept of the compound microscope.
Red flower being crossed with a white flower and creating a pink flower is an example of what
Answer:
With incomplete dominance, a cross between organisms with two different phenotypes produces offspring with a third phenotype that is a blending of the parental traits. It's like mixing paints, red + white will make pink.

Which came first chicken or an egg
Answer:
I think, the egg. Not so sure about it.
Eggs come from chickens and chickens come from eggs: that’s the basis of this ancient riddle. But eggs – which are just female sex cells – evolved more than a billion years ago, whereas chickens have been around for just 10,000 years. So the riddle is easily solved…or is it?
Taken at face value, there is no doubt that the egg came before the chicken. We tend to think of eggs as the shelled orbs laid by birds from which their chicks hatch – unless we eat them first. But all sexually reproducing species make eggs (the specialised female sex cells). That’s 99.99 per cent of all eukaryotic life – meaning organisms that have cells with a nucleus, so all animals and plants, and everything but the simplest life forms.
We don’t know for sure when sex evolved but it could have been as much as 2 billion years ago, and certainly more than 1 billion. Even the specialised sort of eggs laid by birds, with their tough outer membrane, evolved more than 300 million years ago.
As for chickens, they came into being much later. They are domesticated animals, so evolved as the result of humans purposefully selecting the least aggressive wild birds and letting them breed. This seems to have happened in several places independently, starting around 10,000 years ago.
The wild ancestor of chickens is generally agreed to be a tropical bird still living in the forests of Southeast Asia called the red junglefowl – with other junglefowl species possibly adding to the genetic mix. From these origins, humans have carried chickens around the world over the past two millennia or more.
So, eggs dramatically predate chickens. But to be fair to the spirit of the riddle, we should also consider whether a chicken’s egg predates a chicken. As humans consistently chose the tamest red junglefowls and bred them together, the genetic makeup of the resulting birds will have shifted. At some stage during this domestication process the red junglefowl (Gallus gallus) evolved into a new subspecies, Gallus gallus domesticus, AKA the chicken.
In practice, it is impossible to pinpoint the moment when this happened. But in theory, at some point two junglefowl bred and their offspring was genetically different enough from the species of its parents to be classified as a chicken. This chicken would have developed within a junglefowl egg and only produced the very first chicken’s egg on reaching maturity. Looked at this way, the chicken came first.

1. What is apoptosis and what does it have to do with cancer cells?
2. What is the purpose of the Bcl‑2 proteins?
3. What is and oncogene and what can we gain from studying them?
Answer:
1.Apoptosis in Cancer
The loss of apoptotic control allows cancer cells to survive longer and gives more time for the accumulation of mutations which can increase invasiveness during tumor progression, stimulate angiogenesis, deregulate cell proliferation and interfere with differentiation [2].
2.BCL-2 family proteins are the regulators of apoptosis, but also have other functions. This family of interacting partners includes inhibitors and inducers of cell death. Together they regulate and mediate the process by which mitochondria contribute to cell death known as the intrinsic apoptosis pathway.

The relative age of a fossil can be determined by comparing its ________ to other fossils within the same rock layers below younger fossils.
Answer:
The relative age of a fossil can be determined by comparing its Index fossils to other fossils within the same rock layers below younger fossils.
Explanation:
Relative dating is one of the two methods used to determine the age of fossils does not determine when events occur, but it shows the order of the events as they occur. Relative dating compares similar rocks and fossils of already known ages to the ones the fossils that are yet to be determined so as to get their approximate age. The relative age of a rock is the age of that rock when compared to the ages of other rocks.
A fossil record can show the relationship that existed between different plants and animals. Often we Index fossils are used in dating other fossils found in the same strata. Index fossils point out the relative age of the layer where it is found,

Nuclear Power and drilling for oil & natural gas can both negatively affect ecosystems. Which negative impact can only be caused by nuclear power?
A. Air pollution
B. Water Contamination
C. Exposure to radioactive elements
D. Spread of invasive species.
Answer: B
Explanation:
Answer:
C exposure to radioactive elements
Explanation:
The main concern of using nuclear power is the radioactive elements it creates. An example would be uranium.
Sure natural gas is bad for the environment but its no where near as harmful as exposure to radioactive
Drilling for oil does not release radioactive elements therefore exposure to radioactive elements can only be caused by nuclear power.

Is mammalian a parasite ?
Answer:
The short answer is, yes and no. There's only a handful of animals like mammals or birds that have a parasitic relationship; one such is the Vampire Bat, yes, although one could argue it could also be considered a form of hunting too.
Explanation:
Answer:
mammals. are essentially all insects and their allies which live on the skin or in its superficial layers. The latter consist of one-celled animals or protozoa, and vari- ous types of parasitic worms, as well as certain insects and their allies.
What types of health related issues might be associated with climate related factors?
A) malaria
B)
skin cancer
C) hypothermia
D) elevation sickness
E) all of the above
Answer:
E) All of the above
Explanation:
Malaria, is caused by mosquito bites, and mosquito's follow warmth, so if climate changes to warm really quickly more people are likely to get malaria. Skin cancer can be caused by sun radiation, or staying in the sun for to long, so if climate changes again to really warm, you can get skin cancer if not careful. If your to hot you can go in hypothermia shock. And if the elevation increases or decreases to quick you can get elevation sickness. All of these options change, because of the climate around them, therefore the answer is E. I hope this helps :)

Two students are discussing natural selection in bacteria and how it can relate to antibiotic resistance in bacteria.
Bernadette states that when antibiotics are used, bacteria can respond by developing traits to help them defeat the antibiotic, which then may increase their fitness.
Dominique states that there is already a variety of traits among the bacteria. Bacteria that have traits that allow them to survive the antibiotic and reproduce may have higher fitness.

Why does temperature change always move from regions of hot to regions of cold?
When two bodies with different temperatures come into thermal contact, they exchange heat energy until they attain thermal equilibrium, at which point the cold body warms up and the hot body cools down.
What is thermal conduction?The process by which heat is transmitted from an object's hotter end to its colder end is known as conduction.
The term "thermal conductivity" refers to an object's capacity to transfer heat, and it is represented by the letter k. Heat naturally moves in the direction of a temperature gradient.
Thermal conduction is the term used to describe the flow of energy (heat) caused by temperature variations between nearby body parts.
The kinetic energy of the atoms in hot bodies is higher than that of the atoms in cold bodies.
The higher kinetic energy atoms attempt to move and collide with the lower kinetic energy atoms in order to preserve thermal equilibrium. As a result, heat can be transferred from a hot body to a cold body.
Thus, temperature change always move from regions of hot to regions of cold.
