You look at the cell under a microscope and see that it has 34 body chromosomes and one nucleus. Second view: Several hours later, you look at the same cell again and see that it has double the amount of DNA and one nucleus. Third view: A little while later, you see that it has one cell with 68 chromosomes and two nuclei. What stage of the cell cycle was this cell in when you viewed it at each time point
The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called... *
Answer:
Phylogenetic tree
Explanation:
A phylogenetic tree is a tree that is responsible for showing the different relationships with respect to evolution between species that are considered to have a common offspring. The species of interest are shown at the tips of the branches of the tree in question. The branches are connecting with each other, representing the evolutionary history of the species, being the way in which we think that they evolved starting from a common ancestor through various divergence events (when two branches separate).
Describe what the male beetle has to do In order to successfully mate with the female
Answer: they would maybe have to fight with the other beetles to tr and get the females attention
Explanation:
pls mark brainliest
The male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.
How do beetles mate?Female beetles of this species dig tunnels in the dung, where males mate with them. If a male enters a tunnel that is already occupied by a rival, they will fight, trying to pull the other out.
With this information, we can conclude that the male beetle must struggle to successfully mate with the female if where they go there is more than one male courting the female.

Answer:
DNA is the recipe for how to build your body's proteins and mRNA is an index card it copies the DNA but doesn't have to stay in the nucleus. (1st option)
Explanation:
DNA carries genetic instructions for developing, growing and reproducing all known organisms and many viruses. mRNA, on the other hand, collects the DNA's instruction to the cells' protein-making part.

Which of the following conclusions is most likely true if a region experiences unusually low daily temperatures for the season?
the seasonal total of GDD units will be lower than average
the accumulated GDD units still needed to ripen a crop will fall
the average daily value of the GDD will rise
the Tbase value for a particular crop will rise
Answer: D
Explanation: Because if it is going to be cold out every day, the plants aren't gonna grow. So that means the crop rarity will go up, and people would take advantage, and sell them for more of a value.
what are the pro and cons of pollution
Answer:
Cons: Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Humans are also regularly harmed by pollution. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases What are the pros of pollution?
However, there may be some small advantages to air pollution:
Air pollution helps plants grow. Guess what our factories and cars put in the air? ...
Air pollution slows climate change. Some pollutants we put out heat up the Earth, like carbon dioxide. ...
Air pollution keeps polluted cities cooler in the summer.
n 1960, an invasive species of fish was introduced into the stable ecosystem of a river. Since then, the population of a native fish species has declined. This situation is an example of an
1) Ecosystem that has recovered
2) Ecosystems are altered through the activities of humans.
3) Environmental impact caused by physical factors
4) Ecological niche without competition
This situation is an example of 'ecosystems are ALTERED through the activities of humans' (Option 2).
Human activities (i.e., anthropogenic activities) represent the main factor capable of affecting the homeostasis of the ecosystems.Some human activities that negatively alter a natural ecosystem include deforestation for different purposes (e.g., urbanization, agriculture, etc), the introduction of non-native invasive species, pollution, etc.These activities may trigger serious problems to the environment such as soil erosion, climate change, undrinkable water, etc.In conclusion, this situation is an example of 'ecosystems are ALTERED through the activities of humans'.

Imagine you are talking to a friend who says "oh that animal has the most muscles and is the strongest so it will survive. That's what survival of the fittest means." Explain to your friend why they are wrong and what the true, scientific meaning of the phrase "survival of the fittest" means. Your answer should include the following vocab: natural selection, adaptation, evolution, genetic variation
Answer: I would say survival of the fittest means the continued existence of organisms which are best adapted to their environment, with the extinction of others, as a concept in the Darwinian theory of evolution. I do not the the answers to the rest sorry
Explanation: What if I dont want to imagine XD
Answer:
Muscle mass isn'y always a genetic trait, for instence I could work out a bounch and become ripped. if I have kids they could still be couch potatos. That is because traits aquired in ones own life are not passed on, it is the mutations you posses from birth that are passed on if the envirorment aproves of them. If you have lots of muscles and are strong you are not nessisarly more likely to survive anyway, because how are you gonna run away from a lion when youve got all these arm muscles waying you down.
Horses and donkeys can breed and produce sterile offspring known as mules. Horses and donkeys remain separate species because of this hybrid sterility, which is a(n) Group of answer choices post-zygotic barrier to reproduction. sympatric barrier to reproduction. pre-zygotic barrier to reproduction. allopatric barrier to reproduction. good thing.
Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.
What happens when two haploid
gametes are combined during
fertilization?
A. The cell doubles in size.
B. The diploid number is restored to the zygote.
C. The cell immediately fuses to any cell any the
vicinity
Answer:
Option B is the correct one
Explanation:
Fertilization between the haploid gametes forms a diploid zygote. ... Haploid (1n) spores germinate and undergo mitosis to produce a multicellular gametophyte (1n). Specialized cells of the gametophyte undergo mitosis to produce sperm and egg cells (1n), which combine in fertilization to make a zygote (2n)
Explique de qué manera la deriva continental ha influido en la distribución de especies vegetales y animales en el mundo.
Answer:
la deriva continental ha notablemente influido en la distribución actual de las especies. Este fenómeno se puede observar en grupos de organismos similares que se encuentran en diferentes continentes, lo cual concuerda con la idea de que la separación entre dichos continentes se produjo más tardíamente en el tiempo
Explanation:
La teoría de la deriva continental plantea que durante el final del Paleozoico y el principio del Mesozoico (hace aproximadamente hace 225 millones de años) las masas continentales actuales se encontraban unidas formando una gran masa de tierra o supercontinente conocido como 'Pangea'. Esta teoría se basa en evidencia de diversa fuentes incluyendo pruebas geográficas (coincidencias en las costas de algunos continentes), paleontológicas (mismos fósiles en diferentes continentes), geológicas y tectónicas (por ej., la presencia de cadenas montañosas que se separaron hace millones de años), y paleoclimáticas (evidencia de climas similares durante el pasado en continentes diferentes). La deriva contiental afectó la distribución actual de especies de plantas y animales. Por ejemplo, la fauna en Europa es semejante a la observada en Norteamérica porque estos continentes se separaron más tardíamente en el tiempo que otros contientes/masas de tierra del hemisferio sur, y dichas semejanzas se encuentran reflejadas en organismos evolutivamente más relacionados (menor tiempo de divergencia evolutiva).
