Answer: 1. By dating the rocks in Earth's ever-changing crust, as well as the rocks in Earth's neighbors, such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years. Related: How Big is Earth? 2. Scientific evidence relies on data, and it is crucial for researchers to ensure that the data they collect is representative of the “true” situation. This means using proved or appropriate ways of collecting and analysing the data and ensuring the research is conducted ethically and safely. Fossil evidence shows the changes in lineages over millions of years, such as in hominids and horses. Studying anatomy allows scientists to identify homologous structures across diverse groups of related organisms, such as leg bones. Vestigial structures also offer clues to common ancestors.
Explanation:
Answer: There are many different ways we can determine the earth's age. 2 pieces evidences that help apporximate the age of the earth is the dating of the rocks and fossils. Also dating the rocks in Earth's neighbors, like the moon and visiting meteorites.
Scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years
Explanation: if you look and date the rocks in the earth's crust and the moon and meteorites that could give us a date of how old the earth is becuase the rocks and fossils have been here for a long time.

En una botella metálica tenemos un gas a 15°C y una presión de 7.5 atmósferas. Si la presión máxima que aguanta la botella es de 12.5 atm, calcular cuál es la temperatura máxima a la que se puede calentar el gas de su interior. Actividad
Answer:
207 ° C
Explanation:
De;
P1 / T1 = P2 / T2
Luego;
P1T2 = P2T1
P1 = I presión inicial = 7.5 atmósferas
T1 = temperatura inicial = 15 ° C + 273 = 288K
P2 = presión final = 12,5 atm
T2 = temperatura final =?
T2 = P2T1 / P1
T2 = 12,5 * 288 / 7,5
T2 = 480 K -273
T2 = 207 ° C

Which of the following events happens during anaphase?
Menstruation occurs when.
an unfertilized egg is expelled from the body
a fertilized egg is nonviable and is expelled from the body
a fertilized egg moves to the uterus.
the lining of the uterus is shed because an ovum has not been fertilized
The menstrual cycle is referred to as a natural transition that takes place in a female's reproductive system, due to the lining of the uterus being shed because an ovum has not been fertilized, hence option D is correct.
What is menstruation?Specifically in the uterus and ovaries, which enable conception. This cycle, which is controlled by hormonal changes, is crucial for producing oocytes and preparing the uterus to carry a fetus.
The follicular phase, ovulation, and luteal phases are the three phases that make up the menstrual cycle.
The uterus builds a wall on the uterus each month to protect and feed the fertilized egg as the body gets ready for pregnancy.
Therefore, in order to rid the uterus of any potential infections, the body will remove the accumulation in the lining when an ovum is not fertilized during monthly menstruation.

A. The lower fins look like the legs of a turtle. B. The mouth on the fish looks like the bottom of a lake. C. The stripes on the fish look like the plants in the water. D. The upper fin looks like another fish. PLEASE HELP
The stripes on the fish look like the plants in the water describes how this fish is adapted to live in the weedy areas in freshwater lakes. So, the correct option is C.
What is Adaptation?An organism or species adjusts to alterations in its environment through the process of adaptation in order to live and procreate. This can be done in a number of ways, including by altering behaviour, physiology, or physical traits.
Adaptations might be structural, like an organism's physical characteristics, or functional, like the biochemical or physiological systems that enable an organism to perform specific functions. the example provided above, The fish's stripes serve as camouflage and aid in its ability to blend in with its surroundings since they imitate the vertical stems of aquatic vegetation. The fish can sneak up on prey and avoid being observed by predators thanks to its adaption.
Therefore, the correct option is C.

Answer:
Explanation: Amphibian axis formation is an example of regulative development. The most important clue came from the fate map of this area of the egg, for it. Therefore, the specification of the dorsal-ventral axis begins at the moment of sperm entry. The Siamois protein is critical for the expression of organizer-specific genes

Which of the following is a
process that organisms use
to combine two cells to
create one cell, thus
creating a new organism?
A. Asexual reproduction
B. Sexual reproduction
C. Mitosis
D. Somatic cells
Answer:
B. Sexual reproduction
Explanation:
Reproduction in living organisms, which is the process of creating new copies of a particular species, can occur asexually or sexually. The asexual method of reproduction involves only one organism however, the sexual reproduction involved two organisms of different sexes (male and female).
In sexual reproduction, the male organism produces male gametes (sperm) while the female organism produces female gamete (egg). These two sex cells or gametes come together in a process called FERTILIZATION to form one new cell called ZYGOTE, which eventually develops into a new organism.

4. Is it possible for a child to have a DNA band that is not found in the
mother's DNA? Explain your answer.
Answer:
1. Which baby belongs to the Meanys?
Baby 3 belongs to Meanys because in the DNA profiling method, their DNA bands matched with the second baby.
2. Which baby belongs to the Glicks?
Baby 1 belong to Glicks because in the DNA profiling method their DNA bands matched with the second baby.
3. Which baby belongs to the Moes?
Baby 2 belong to Moes because in the DNA profiling method their DNA bands matched with the second baby.
4. Is it possible for a child to have a DNA band that is not found in the
mother's DNA? Explain your answer.
Yes, it is possible for a child to have a DNA band that is not found in the
mother's DNA.
Explanation: It is possible because in the DNA of the baby, 50% of the baby's genome is likely to be recombinant due to crossing over occuring between the maternal and paternal chromosomes.
As a result, this recombinant DNA is the complete new DNA and non-identical from the parents.
